An electronic distance meter comprises a laser emitting a laser pulse toward a target, a photodetector adapted for receiving a laser pulse reflected by the target and for outputting a corresponding return pulse signal, and a comparison circuit receiving said return pulse signal and comprising a comparator provided with a first input and a second input and arranged to output a first fixed value signal when the signal at the first input exceeds the signal at the second input and else to output a second fixed value signal, said comparison circuit being arranged for determining a return pulse time signal based on the output of said comparator, said electronic distance meter being arranged for determining a target distance based on said return pulse time signal.
The comparison circuit comprises a first branch connected to said first input and provided with an integrator which receives a signal derived from said return pulse signal and comprises an output connected to said first input, and a second branch connected to said second input which receives a signal derived from said return pulse signal.
