Can be arranged to form a single bi-aspherical convex lens, which can act as a collimating lenslet 32. FIG. 6B is a diagram of a magnified view of a 2×4 grid of the collimating lens array with collimating lenslets 32 shown in FIG. 6A. FIG. 6C is a diagram of a profile view of a collimating lens array with a laser etched engineered diffuser 34 as shown in FIG. 6A. An engineered diffuser is an advanced light beam shaper capable of homogenizing an input beam and shaping the output intensity profile and the way the light is distributed in space. An engineered diffuser can create non-Gaussian intensity distributions in circular or square beam profiles that diverge from the plane of incidence. Engineered diffusers can be, for example polymer-on-glass such as replicated polymer on a glass substrate, an etched hard material such as fused silica, silicon, or germanium, with plastic embossing, injection-molded plastic components, or micro-optical elements on a flexible substrate. Some specific examples of engineered diffusers are laser-etched diffusers and engineered holographic diffusers. FIG. 6D is a diagram of a close-up isometric view of a single collimating lenslet 32 in a collimating lens array shown in FIG. 6A. FIG. 7A is a diagram of a diffuser 36 which can optionally be in the projector device downstream the collimating optical system along the ray path. In this embodiment, the diffuser 36 is laser etched engineered diffuser which functions to scatter the light rays. In some examples, the diffuser 36 is a single diffuser lenslet or diffuser lenslet array as shown in FIG. 7C. In one implementation of the present disclosure, the diffuser 36 has a circular angle of 3.5 degrees and does not require coating. FIG. 7B is a magnified diagram of a laser etched engineered diffuser 34, magnified as section

To the adjacent pixel, and results in no overlap in the pixels. The projection optical system 14 is placed such that the distance between the projection optical system 14 and the collimating lens array 26 creates a projected image equal in size to a single lenslet in the collimating lens array 26. A collimated light beam 30 leaving the collimating lens array 26 travels to the diffuser 36. In some examples, the diffuser 36 can comprise an engineered diffuser array, or one or more lenses, optical mirrors, or optical materials that may be suitable for diffusion. The diffuser 36 is positioned between the collimating lens array 26 and the display optical system 22, and the diffuser 36 receives light from the collimating lens array 26. The collimating lens array 26 and the diffuser 36 can be a single integrated piece, or separate pieces. The display optical system 22 can be positioned to receive a second projected image 20 from the diffuser 36. Therefore, light from the collimating lens array 26 travels to the diffuser 36 which in one example is an engineered diffuser array. The output light rays forming a first projected image 16 from the projection optical system 14 are collimated to preserve the projected size of the image. At the diffuser 36, the divergence of each pixel is increased by a factor of: √{square root over (C2·fm2)} where C is a constant that is chosen for proper reconstruction of the sampled wavefront and fm is a fill factor. In one example, the value of C is approximately 2. In such instances the fill factor, fm, is approximately 0.9, such that the spot size, xs, is related to the pixel spacing, xp, as xs=xp·√{square root over (C2·fm2)} where xp is the lens pitch divided by the number of angular

Samples. Therefore, the diffuser 36 imparts a point spread function on each pixel in the image. The pixels with the point spread function from the diffuser 36 are then incident on the back surface of the display optical system 22, which constitutes the display lens. As the light is incident on and passes through the diffuser 36, the light is dispersed according to a point spread function, approximated as a Gaussian function. The diffuser 36 may include an angular diffuser or engineered diffusing array which is used to achieve a desired spread function and prevent bleed from the projection of light from neighboring pixels. In one example, the projection optical system 14 creates an image having a size of 20 mm×10 mm at a distance defined by the throw ratio of the projector, where the throw ratio is the ratio of the distance from the lens to the screen (throw) to the screen width. This image may then be projected to a collimating lens array 26, resulting in a packet image that is the exact size (20 mm×10 mm) projected toward the diffuser 36, which is, for example, a diffuser screen or engineering diffuser array. The diffuser 36 can then create a small, defined point spread function. Using the desired point spread function, proper overlap between pixels is achieved to reduce resolution bias error or the picket fence effect and distribute the light for a better viewing experience. Resolution bias error references missing information between samples in a spectrum. The reduction of the resolution bias error allows for smooth viewing zone transitions. The diffuser 36 in this instance is designed to a very specific angular output such that if, for example, the engineered divergence has a 5-degree circular FWHM, the beam through the optical system will also have an intensity

OperationsPress once: Diffuse continuously until it runs out of water. Press twice: Diffuse for 30 minutes and then shut off. Press three times: Diffuse at 5 minutes on/5 minutes off intervals until it runs out of water. Press four times: Diffuse for 30 seconds on/30 seconds off intervals until it runs out of water.Battery LED Indicator: - Charging (cool white light) - Full Battery (warm white light) - Low Battery (flashing warm white light)Always disconnect the AC adaptor from the device and power off the device before cleaning. Hold the base and rotate counterclockwise to take off the outer cover. Pour the water out from the opposite side of the ventilation hole.This diffuser measures approximately 2.75 inches in diameter. For best results when used on the road, please ensure the diffuser fits snugly into your cupholder. Any jostling or tipping of the diffuser may cause the water inside to activate the diffuser's safety sensor, causing it to shut off operations. How To CleanUse a clean cloth and neutral cleanser to wipe down the reservoir. Then rinse with clean water and wipe dry with a cloth. We recommend cleaning your diffuser twice a week when used regularly. Cautions: This product is not a toy. Not to be operated by children. Use under adult supervision only. Always place the diffuser on a flat, stable surface to prevent water spillage. If using in a moving vehicle, ensure the diffuser fits snugly into your cup holder.Any jostling or tipping of the diffuser may cause the water inside to activate the diffuser’s safety sensor, causing it to shut off operations and potentially damaging the diffuser.Always ensure the diffuser is turned off and not connected to the USB cable before filling the water reservoir. Do not fill the diffuser past the red marker line to prevent excess water from interfering with the diffuser’s functions. Be careful not to let any water get into the USB port. If water does get into the USB port, we recommend wiping the area dry and allowing the diffuser to sit for a few hours before use.Before inserting the USB cable, ensure it is completely dry by wiping it with a clean, dry cloth. Remove the USB cable once the device is fully charged. Always keep the diffuser dry when not in use. If smoke or a burning smell is detected, unplug the diffuser immediately. Ultrasonic diffusers are designed to be used with US voltage and plugs - an adapter may be needed for international customers.These statements have not been evaluated by the Food and Drug Administration.

Be a single integrated piece or separate components, either of which forms a collimating optical system 18. The display optical system 22 can be positioned to receive a diffused, collimated beam from the collimating optical system 18. Therefore, light from the collimating lens array 26 travels to the diffuser 36, which in one example is an engineered diffuser lenslet array. The output of the projector is collimated to preserve the projected size of the image. At the diffuser 36, the divergence of each pixel is increased by a factor of: √{square root over (C2·fm2)} where C is a constant that is chosen for proper reconstruction of the sampled wavefront and fm is a fill factor. In one example, the value of C is approximately 2. In such instances the fill factor, fm, is approximately 0.9, such that the spot size, xs, is related to the pixel spacing, xp, as xs=xp·√{square root over (C2·fm2)} where xp is the lens pitch divided by the number of angular samples. Therefore, the diffuser 36 imparts a point spread function on each pixel in the image. FIG. 14 is a graphical illustration of said point spread function. The pixels with the point spread function from the diffuser 36 are then incident on the back surface of the display optical system 22, which constitutes a display lens. The distance between the display optical system 22 and collimating optical system 18 will allow for fine tuning of the output width of the pixels per image and may be minimized to reduce system space. As the light is incident on and passes through the collimating lens array 26, the light is dispersed according to a point spread function, approximated as a Gaussian function. The diffuser 36 may include an angular diffuser or engineered diffusing lenslet array which is
