Abstract: A near-eye optical display system utilizes a compact display engine that couples image light from an imager to a waveguide-based display having diffractive optical elements (DOEs) that provide exit pupil expansion in two directions. The display engine comprises a pair of single axis MEMS (Micro Electro Mechanical System) scanners that are configured to reflect the image light through horizontal and vertical scan axes of the display system's field of view (FOV) using raster scanning. The MEMS scanners are arranged with their axes of rotation at substantially right angles to each other and operate with respective quarter wave retarder plates and a polarizing beam splitter (PBS) to couple the image light into an in-coupling DOE in the waveguide display without the need for additional optical elements such as lenses or relay systems.

Abstract: The present application discloses a 3D imaging method and apparatus, which divide a source 3D image light into two polarized light beams carrying image information through a birefringence effect, adjust optical paths of the two polarized light beams obtained through birefringence, and control the two polarized light beams to be alternately irradiated, thereby achieving 3D imaging; since the implementation of the above imaging method only requires one imaging apparatus having corresponding functions, the present application can simplify the system structure and reduce the system cost relative to a conventional 3D projection technology that requires two imaging devices; moreover, a viewer can directly see, with no need to wear corresponding 3D glasses, a 3D image due to the parallax caused by alternate irradiation of two polarized light beams carrying image information out of a projection device. As a result, the investment in configuring 3D glasses can be saved and the system cost is further reduced.

The imager includes a beam deflector to deflect light beams within the imager, a light source with an active surface, to emit light beams in the direction of the beam deflector, a reflector with a main plane, to reflect incident light beams from the direction of the beam deflector in the direction of the beam deflector, a light modulator with an active surface, to modulate incident light beams from the direction of the beam deflector and to reflect them in the direction of the beam deflector. The beam deflector is between the reflector and the light modulator.

Abstract: In an illumination system (12, 13) for a scatterometer, first and second spatial light modulators lie in a common plane and are formed by different portions of a single liquid crystal cell (260). Pre-polarizers (250) apply polarization to first and second radiation prior to the spatial light modulators. A first spatial light modulator (236-S) varies a polarization state of the first radiation in accordance with a first programmable pattern. Second spatial light modulator (236-P) varies a polarization state of the second radiation accordance with a second programmable pattern. A polarizing beam splitter (234) selectively transmits each of the spatially modulated first and second radiation to a common output path, depending on the polarization state of the radiation. In an embodiment, functions of pre-polarizers are performed by the polarizing beam splitter.
