摘要： An optical image modulator and a method of manufacturing the same. The optical image modulator includes a substrate, an N electrode contact layer formed on the substrate, a lower distributed Bragg reflection (DBR) layer, a quantum well layer, an upper DBR layer, and a P electrode contact layer sequentially stacked on the N electrode contact layer, a P electrode formed on the P electrode contact layer, and an N electrode formed on the N electrode contact layer. The N electrode is a frame that surrounds the lower DBR layer.

摘要： In embodiments, a T-O-F depth imaging device renders a depth image of an object that has corrected depth values. The device includes a pixel array that uses an Electronic Rolling Shutter scheme. The device also includes a light source that transmits towards the object light that is modulated at an operating frequency, and an optical shutter that opens and closes at the operating frequency. The optical shutter further modulates the light that is reflected from the object, before it reaches the pixel array. The transmission of the light and the operation of the shutter change phase relative to each other while at least one of the pixels is sensing the light it receives, which permits a faster frame rate. Depth is determined by the amount of light sensed by the pixels, and a correction is computed to compensate for the changing phase.

摘要： An apparatus and method for generating a depth image are provided. The apparatus includes an optical modulator, an optical sensor, and a depth image processor. The optical modulator optically modulates light which is reflected from an object to which light modulated using a first pseudorandom (PN) sequence is irradiated. The optical modulator optically modulates the reflected light using second PN-sequences, where each of the second PN-sequences has a same PN sequence as the first PN-sequence, but the second PN-sequences have N different time shifts. The optical sensor senses the optically modulated reflective light. The depth image processor samples N intensity images from the optically modulated reflective light sensed by the optical sensor and generates a depth image of the object using the sampled N intensity images.
