Abstract
A light receiver circuit with compensation of propagation times has at least one light sensor, one control circuit, one connecting line to a TDC circuit, and a test circuit. The test line is connected to a test signal source. The test circuit connects the test line to the control circuit and forwards the test signal to the control circuit. The control circuit routes a measurement signal of the light sensor to the TDC circuit and a test signal to the connecting line and to the TDC circuit to evaluate the test signal and propagation time of test signal from test circuit to TDC circuit. The light sensor array further includes a plurality of light receiver circuits of such kind. The invention also relates to a Lidar receiver for capturing optical events with a light sensor array with a TDC circuit and a test signal source and with a timecode generator.
