Abstract
An image sensor comprises a plurality of pixels (Pix), each comprising an elementary photodetector (), wherein each pixel (Pix) comprises a circuit () for detecting a beat frequency of a portion of a heterodyne beam received by the elementary photodetector () of the pixel, and wherein, in each pixel (Pix), the detection circuit () comprises a frequency comparator () comprising a first input node (E) receiving a first periodic AC signal (f) having a frequency equal to the beat frequency, a second input node (E) receiving a second AC signal (f) of variable frequency, and an output node (S) delivering an output signal switching from a first state to a second state when the frequency of the second signal (f) exceeds the frequency of the first signal (f).
