摘要： Described is an optical projection and capture system having an image sensor integrated with an optical projection device. Additionally, the integrated device may be coupled with a laser pointer to deliver interactive presentations. The laser pointer may be pulsed to improve identifying and tracking a laser light spot on a projected image. These applications may be extended to rear projection systems for gaming and interactive graphics.

摘要： An optical proximity sensor often emits light, and detects the photons in the returned light signal. Because light can be reflected and scattered by cover glass and ink layer printed on the cover glass, optical crosstalk is a concern for the optical proximity sensors. In one embodiment, the present disclosure provides an optical proximity sensor including a linear polarizer to cover the photo detector, or a polarizer to cover the light emitting device, or two polarizers to cover both the photo detector and the light emitting device. The polarizer blocks the s-polarized light and only allows the p-polarized light to pass through. Because the scattered light is predominated by the s-polarization, the optical crosstalk may be reduced.

摘要： System and method for simultaneous display of multiple images using a single light modulator array. A preferred embodiment comprises a light source that produces a light with desired spectral characteristics, a color filter optically coupled to the light source, and an array of light modulators optically coupled to the color filter. The color filter filters light from the light source to produce light of desired wavelengths and the array of light modulators simultaneously displays multiple images onto a display plane. Portions of the array of light modulators are designed so that each portion can independently display an image and the light source provides needed light to display the image.
