Regularities of Formation of the Visibility Zone by Active-Pulse Vision Systems with a Comparatively Short Duration of Photodetector Exposure

Abstract

A model for forming a range-energy profile (REP) of the visibility zone for an object stationary relative to the system when the duration of the photodetector strobe pulses (exposure time) is significantly shorter than the duration of laser pulses illuminating the objects was proposed. Analytical expressions were derived linking the characteristic distances (points) of the visibility zone REP with the durations of strobe pulses, the uncontrolled technical delay, and the parameters of the laser pulses for different temporal shapes. Numerical calculations confirmed the validity of the obtained analytical expressions. It was established and experimentally confirmed that the REP, taking into account certain patterns, reproduced (displayed) the temporal shape of the laser pulse following from its beginning to its end when moving from the initial point of the visibility zone to the final point.
