CONTROLLABLE GATED SENSOR

摘要

A single pixel sensor is provided, comprising a photo sensor configured to convert light into proportional signals; a charge storage configured to accumulate, repeatedly, a plurality of the signals converted by the photosensor; a first transistor coupled between a pixel voltage terminal and the photosensor; a second transistor coupled between the photosensor and the charge storage; and a readout circuit coupled between the charge storage and an output channel, wherein: the single pixel sensor is configured to carry out the repeated accumulations of signals multiple times per each readout by the readout circuit to synchronously convert reflections of light emitted by the illuminator, and to carry out at least one of the repeated accumulations of signals in at least partial overlap with at least one light pulse generated by the pulsed illuminator.
