Abstract

"Sistema lidar coherente monoestatico con detección heterodina (SLCM-H) de baja potencia para medida de velocidad lineal y de rotación de blancos sólidos". La invención se refiere a un prototipo para un sistema lidar coherente capaz de medir la velocidad de blancos sólidos a una distancia de 2m., el principio de funcionamiento se basa en la detección del desplazamiento Doppler producido en la frecuencia de la radiación dispersada por un blanco, iluminado por el sistema, para conseguir una detección heterodina, se desplazan tanto la señal transmitida como la recibida empleando un modulador acusto-óptico, el rango de velocidades que es capaz de medir llega hasta unos 40 km/h en ambos sentidos, empleándose un transmisor láser de HeNe de baja potencia, un sistema óptico que permite el acondicionamiento y procesado de las señales transmitida, recibida y del oscilador local y un receptor con un fotodiodo y una electrónica de amplificación."Monostatic coherent lidar system with heterodyne detection (SLCM-H) of low power for measurement of linear velocity and rotation of solid targets". The invention refers to a prototype for a coherent lidar system capable of measuring the speed of solid targets at a distance of 2m. The operating principle is based on the detection of the Doppler shift produced in the frequency of the radiation scattered by a target. , illuminated by the system, to achieve heterodyne detection, both the transmitted and received signals are moved using an acousto-optic modulator, the range of speeds that it is capable of measuring reaches up to 40 km/h in both directions, using a low power HeNe laser transmitter, an optical system that allows the conditioning and processing of the transmitted, received and local oscillator signals and a receiver with a photodiode and amplification electronics.
