Abstract

UN DISPOSITIVO DE MEDIDA DE DISTANCIA DE UN DIODO LASER INCLUYE UN DIODO (10) LASER EL CUAL EMITE LUZ (20) PARA UNA LENTE (22) LA CUAL PROPORCIONA ILUMINACION (24) FOCALIZADA QUE INCIDE SOBRE UN OBJETIVO (26). LA LUZ (24) SE REFLEJA DESDE EL OBJETIVO DEVUELTA AL DIODO LASER (10), LO CUAL OCASIONA QUE EL DIODO (10) LASER EMITA UNA LUZ (28) LA CUAL EXHIBE IMPULSOS DE INTENSIDAD (DEBIDO A INTERFERENCIA COHERENTE) RELACIONADOS CON LA DISTANCIA (L) AL OBJETIVO (26). UN FOTODETECTOR (30) PROPORCIONA UNA SEÑAL DE REALIMENTACION INDICATIVA DE LA INTENSIDAD DE LA LUZ (28) PARA UN CIRCUITO (18) DE MEDIDA DE DISTANCIA. EL DIODO LASER (10) ESTA ALIMENTADO POR UNA SEÑAL ASCENDENTE EN RAMPA QUE REDUCE EL PROCESO ELECTRONICO Y EN UNA FRECUENCIA QUE REDUCE EL RUIDO DE LA SEÑAL. EL CIRCUITO (18) DE MEDIDA DE DISTANCIA SUPRIME UNA PORCION DE LA SEÑAL DE REALIMENTACION DURANTE DISCONTINUIDADES DE LA SEÑAL DE ALIMENTACION DEL DIODO LASER PARA MINIMIZAR RUIDO ASOCIADO QUE DISTORSIONA LA MEDIDA DE DISTANCIA.
