Abstract

Un convertidor de imagen de película comprende un diodo (14) láser para emitir un haz (15) láser, una fibra (20) optica, acoplada al diodo (14) láser, para transmitir el haz (15) láser, un mecanismo de exploracion para recibir el haz láser de la fibra (20) optica y explorar el haz láser a través de la hoja de película (12), y un dispositivo (30) de recoleccion de luz para detectar la luz transmitida a través de la hoja (12) de película en respuesta a la exploracion del haz (15) láser a través de la hoja (12) de película. Un oscilador (34) de radiofrecuencia puede proporcionarse para modular el diodo (14) láser de radiofrecuencias para aumentar una anchura espectral del haz láser emitiendo por el diodo (14) láser. La anchura espectral incrementada reduce la interferencia generada por multiples reflexiones del haz (15) láser dentro de la hoja (12) de película.
