Abstract

LAS FUENTES DE RUIDO OPTICO CONOCIDAS ESTAN EQUIPADAS CON UNA FUENTE LUMINOSA Y UN FILTRO DE INTERFERENCIA, ACOPLADO OPTICAMENTE A ESTA Y BASADO EN LA DIFERENCIA DE LONGITUD DE TRAYECTORIA, PARA GENERAR UNA SEÑA DE COMPOSICION OPTICA. SI EL ESPECTRO DE UN FOTODIODO A ILUMINAR CON LA SEÑAL OPTICA HA DE SER TAN PLANO COMO POSIBLE, DICHA DIFERENCIA DE LONGITUD DE TRAYECTORIA DEBE SER CONSIDERABLEMENTE MAYOR QUE LA LONGITUD DE COHERENCIA DE LA FUENTE LUMINOSA QUE EN LA PRESENTE PRACTICA CONDUCE A DIFERENCIAS DE LONGITUD DE TRAYECTORIA AMPLIAS DESVENTAJOSAS. AL ALIMENTAR, SEGUN LA INVENCION, UNA SEÑAL DE RUIDO A LA FUENTE DE LUZ, LA LONGITUD DE COHERENCIA DE LA FUENTE DE LUZ DISMINUYE COMO RESULTADO DE LO CUAL BASTA CON USAR DIFERENCIAS DE LONGITUD DE TRAYECTORIA CONSIDERABLEMENTE MENORES.
