    摘要: Active or passive gated-sensor imaging system characterized by a minimized time period between successive sensor exposures. In the active imaging system, a light source emits light pulses toward a region of interest, and an image sensor receives reflections of the pulses reflected from objects located in a DOF to be imaged and converts the reflections into an image. Each frame of the image includes a plurality of gating cycles. Each gating cycle includes the emission of a respective light pulse and the reception of reflections of the respective pulse. A delay-time (TDELAY) is defined as the duration between the sensor exposure periods of successive gating cycles. A controller controls the operation of the light source and the image sensor, to minimize the delay-time for at least one gating cycle of an image frame, where the delay-time is adaptively determined in accordance with at least one system parameter or environmental condition.

    摘要: A system for providing an improved image of daytime and nighttime scene for a viewer within a vehicle is provided herein. The system includes: a pixel array sensor having a fully masked gate-off capability at a single pixel level, wherein the pixel array sensor is provided with an inherent anti-blooming capability at the single pixel level; wherein each pixel is gated by a corresponding transfer gate transistor having high transfer gate efficiency. The system further includes a gating unit configured to control the transfer gate transistors with pulsed or continuous wave modulated active and passive light sources, to yield a synchronized sensing signal from the sensor, wherein a single pulse is sufficient to cover the entire field of view of the sensor and the entire depth of field of the illuminated scene; and a processing unit configured to receive the synchronized sensing signal and process it.
