Abstract (en)
[origin: WO2011121258A1] The invention relates to an analog electronic circuit (2) for processing a light signal (4), which includes: a photodetector (6) suitable for producing an electric signal (8) from the light signal (4); a multiplier (12) suitable for multiplying the electric signal (8) by a reference signal (14) in order to obtain a multiplied signal (16); and an integrator (18) suitable for integrating the multiplied signal (16) over at least one time interval, in order to obtain at least one integrated signal, characterised in that said circuit also includes: an analog memory (24) suitable for storing the integrated signal; and a processing unit suitable for estimating a time correlation of the light signal (4) according to the integrated signal stored in the memory.
