Abstract

Sistema optrónico activo láser que comprende una vía 1) para la emisión de un haz láser de iluminación de un objetivo por una fuente (10) de emisión, una vía (2) para la recepción de la onda retrodifundida por el objetivo y, en la vía de recepción, un dispositivo de conmutación que recibe dicha onda retrodifundida, caracterizado porque - el dispositivo de conmutación es un dispositivo (24) de conmutación óptica que comprende un medio (241) de ganancia óptica y unos medios (242) de bombeo de dicho medio de ganancia, siendo absorbente dicho medio de ganancia a la longitud de onda del láser correspondiente a un modo bloqueado del dispositivo de conmutación y que se convierte en sustancialmente transparente cuando es bombeado en correspondencia con un modo pasante del dispositivo de conmutación, de tal manera que permite la activación del dispositivo de conmutación respectivamente en modo bloqueado o pasante por medio de una unidad (243) de control de los medios de bombeo y porque dicha unidad de control está configurada para controlar la activación del dispositivo de conmutación en modo pasante en al menos una primera ventana temporal de duración predeterminada, activada en un instante (tA) predeterminado después del inicio (t0) de la emisión del haz láser de iluminación, permitiendo limitar en parte un flujo luminoso parásito incidente sobre la vía de recepción.
