ESTACION Y SISTEMA QUE UTILIZAN LA RETRODIFUSION DE RAYOS LASER PARA DETECTAR Y LOCALIZAR UN OBJETO O UNA SUSTANCIA TAL COMO UN HUMO DE INCENDIO

CARACTERIZADA DE MODO QUE LOS DISPOSITIVOS OPTICOS EMISOR Y RECEPTOR ESTAN FORMADOS POR UN SOLO DISPOSITIVO COMPRENDIENDO EN LA DIRECCION DE EMISION UN DISPOSITIVO SEPARADOR (3) DE RAYOS EMITIDOS Y RETRODIFUNDIDOS, UN DISPOSITIVO OPTICO (5) TRANSFORMANDO EL HAZ PARALELO DE POCO DIAMETRO EMITIDO EN UN HAZ DIVERGENTE Y UN TELESCIOPIO (6) ADAPTADO PARA HACERLE CONVERGER EN UN HAZ PARALELO DE MAYOR DIAMETRO, RECORRIENDO EL HAZ RETRODIFUNDIDO ESTE TRAYECTO EN EL SENTIDO INVERSO DEL HAZ EMITIDO. The station's optical transmitting and receiving equipment is incorporated in a single system. In the direction of transmission, the system comprises a device (3) for separating the transmitted and back- scattered beams, an optical component (5) for converting the small diameter parallel transmitted beam into a divergent beam, and a telescope (6) adapted to converge the divergent beam received from the optical component into a parallel beam of larger diameter. The back- scattered beam covers this path in the opposite direction to that of the transmitted beam. Application to the detection of smoke from fires, particularly forest fires.
