ABSTRACT:
A method of detecting a light pulse reflected on an object, including steps of: emitting a light pulse of known intensity and duration towards the object; detecting a reflection signal of the light pulse on the object during a first integration time, wherein, the detecting is carried out with at least one gain sensor that amplifies the reflection signal; on detection during the first integration time, varying an amplification gain of the at least one sensor in a controlled manner so that the amplification gain at each instant of the first integration time is known; and determining a time of return of the reflection signal by evaluating the amplification gain of the reflection signal.
