Abstract: Systems for the manufacturing of waveguide cells in accordance with various embodiments can be configured and implemented in many different ways. In many embodiments, various deposition mechanisms are used to deposit layer(s) of optical recording material onto a transparent substrate. A second transparent substrate can be provided, and the three layers can be laminated to form a waveguide cell. Suitable optical recording material can vary widely depending on the given application. In some embodiments, the optical recording material deposited has a similar composition throughout the layer. In a number of embodiments, the optical recording material spatially varies in composition, allowing for the formation of optical elements with varying characteristics. Regardless of the composition of the optical recording material, any method of placing or depositing the optical recording material onto a substrate can be utilized.

Abstract: There is provided a device for reducing laser speckle comprising: a micro scanner and a holographic diffuser. The micro scanner device comprises: a first transparent optical substrate with an input surface and an output surface; a second transparent optical substrate with an input surface and an output surface and a variable refractive index medium sandwiched between the output surface of the first substrate and the input surface of the second substrate. Transparent electrodes are applied to the output surface of the first substrate and the input surface of the second substrate. The electrodes are coupled to a voltage generator. The input surface of the first substrate is optically coupled to a laser source. The input surface of the second substrate is configured as an array of prismatic elements. Advantageously, at least one of the input surface of the first substrate or the output surfaces of the second substrate is planar. At least one of said transparent electrodes is patterned into independently addressable electrode elements. The average refractive index of any region of said variable refractive index medium is proportional to the voltage applied across the electrode elements sandwiching said region. The micro scanner deflects input light from the laser source into output light at an angle determined by the refractive index of the substrates and the average refractive index of the variable refractive index medium. The voltage applied across each electrode element is varied temporally. Each point in the holographic diffuser diffracts incident light rays of a predefined angle into output light rays having a predefined range of angles to form a diffuse illumination patch.

Abstract: There is provided a method of fabricating an improved HPDLC transparent symbolic data display for projecting symbology into the field of view of a viewing device in which the HPDLC is localized to the display regions covered by the symbols. In a first step, a substrate to which an anti reflection coating and a transparent electrode layer have been applied is provided. In a second step, portions of said transparent electrode layer are removed to provide a patterned electrode layer including a symbol pad. In a third step, a layer of UV absorbing dielectric material is deposited over said patterned electrode layer. In a fourth step, the portion of said UV absorbing dielectric material overlapping said symbol pad is removed. In a fifth step, a second substrate to which an anti reflection coating and a transparent electrode layer have been applied is provided. In a sixth step, the transparent electrode layer of said second substrate layer is etched to provide a patterned electrode layer including an electrode element substantially identical to and spatially corresponding with the symbol pad. In a seventh step, the substrates are combined to form a display cell with the coated surfaces of the two cells aligned in opposing directions and having a small separation. In an eight step, said display cell is filled with a PDLC mixture. In the final step, the cell face formed by the first substrate is illuminated by crossed UV laser beams, and simultaneously illuminating the cell face formed by the second substrate by an incoherent UV source.
