Investigation of the effectiveness of the active pulse method for detecting retroreflective objects

This work describes an experimental study of the effectiveness of hardware-software means for laser pulse location without using an electron-image tube as an external shutter. The system is designed to detect retroreflective objects, including optical and optoelectronic surveillance devices. Results of measurements on a multidimensional scene are presented depending on the position of the active visibility zone of the laser pulse location. It is shown that distances to objects can be determined by processing image sequences obtained using range scanning of a scene and a quadratic approximation of the obtained signal values with the calculation of coordinates of their maxima. A technique for processing the recorded images in order to detect low-contrast objects (with a low retroreflection index) on a complex background is proposed and demonstrated.
