英文摘要 | An optical measurement system is provided for performing time-of-flight distance measurement with ambient light suppression. The system has a detector circuit that includes a photodetector and an additional current gain element that amplifies the photocurrent produced by the photodetector. Placement of the additional current gain element near the photodetector allows low-power optical signals to be detected without amplifying noise from sources of the system that are outside of the detector circuit, thereby allowing a high signal-to-noise ratio to be achieved. Embodiments of the system include circuitry that automatically regulates the bias voltage of the photodetector to compensate for temperature and for fabrication process variations. |
