Abstract

A LIDAR device and method for determining the range of a target surface using a threshold detector circuit that differentiates the laser return signal to define a differentiated signal. The signal level crossing point or threshold is representative of the peak amplitude of the return signal. The device and method compare the signal level crossing point to a predetermined threshold level to determine the range of the target surface in a LIDAR system.
