Latest Patents
Two of David Ezra's latest patents highlight his ingenuity in the field of optical technology. The first patent involves **diffractive, polarization modulating optical devices**. This innovative optical device features an encoding surface with a micro-relief pattern designed to produce a predetermined diffracted first image when illuminated. Additionally, it incorporates an optically anisotropic layer, such as a polymerized liquid crystal, which induces local orientation of the layer to impose a predetermined polarization modulation, yielding a polarization-dependent second image.
The second patent focuses on a **stereoscopic display**. This display utilizes a spatial light modulator, particularly a liquid crystal device, with an array of RGB pixels. A retarder array, positioned in front of the modulator, includes alternating vertical first and second stripes, supplying light to an observer with different polarizations. A lenticular screen positioned in front enhances the viewing experience by aligning with the pixel pitch.
