摘要： A surface measurement module for 3-D image acquisition of a subject-under-inspection. The module having: (a) a casing to house a pattern shifting device having a fixed-pattern optic through which light from a light source is passed, an output of the pattern shifting device being directed at a polarizing beam splitter and the polarized output of the splitter directed through a lens assembly comprising at least one lens element; (b) a reflector to direct the polarized output exiting the lens assembly, to illuminate a surface of the subject-under-inspection; (c) a scattered light illumination off the surface is directed back through the lens assembly for capture by an image sensor; and (d) the casing also housing the polarizing beam splitter, the lens assembly, and the image sensor. The output of the fixed-pattern optic comprises a multi-frequency pattern. The pattern shifting device may be a linear or rotating type.

摘要： An image display system uses a polarizing beam splitter to direct light from a lamp to multiple spatial modulators. The spatial light modulators (“SLM”) each generate an image portion, which are stitched together on a display screen to obtain a high resolution image. In particular embodiment, image portions from two conventional SLMs, each controlling about two million pixels, are stitched together to form an image having about four million pixels. In another embodiment, two lamps are used with four SLMs to produce a resultant image having about eight million pixels.
