TIME-TO-DIGITAL CONVERTER, 3D IMAGER USING SAME, METHOD FOR TIME-TO-DIGITAL CONVERSION AND METHOD FOR 3D IMAGING

摘要

Time-to-digital converter system comprising: an event detector configured for detecting an event and generating an event detection signal upon detection of the event;and a time-to-digital converter coupled or connectable to the event detector and comprising a fine resolution part configured for counting fine time intervals, organized such that the fine resolution part is activated in response to the event detection signal and deactivated in response to a reference clock. 3D imager comprising an array of pixels, with in each pixel such a time-to-digital converter system, and further comprising a reference clock generator.
