Abstract

EN UN DISPOSITIVO DE MEDICION DE LUZ ELECTRICA TAL COMO EL QUE SE PRESENTA EN LA FIGURA 3, SE MIDEN LOS MOVIMIENTOS RELATIVOS ENTRE LA REJILLA (G') Y UN SUBSTRATO (S'). LA RADIACION EMITIDA POR UN LASER SEMICONDUCTOR (L') INTEGRADO EN EL SUBSTRATO (S'), SE CONDUCE A TRAVES DE UNA LENTE CONDUCTORA DE ONDAS (WL') Y UNA REJILLA DE DESACOPLADO (AG') SOBRE LA REJILLA (G'), DONDE SE INCLINA Y DEVUELVE AL SUBSTRATO (S'). EL HAZ DE RAYOS INCLINADO (+M' -M') SE PRESENTA POR LOS ELEMENTOS DE ACOPLAMIENTO (+H' -H') Y LA REJILLA DE ACOPLAMIENTO (+HG' -HG'), SE RECOJEN MEDIANTE CONDUCTORES DE ONDAS DE LUZ (+LWL' - LWL') EN UN ACOPLADOR (TBJ') Y PASAN A LA INTERFERENCIA. DEL ACOPLADOR (TBJ') SE CONDUCEN A TRAVES DE CONDUCTORES DE ONDAS DE LUZ A LOS DETECTORES (+D',D'. -D'), QUE LOS TRANSFORMAN EN SEÑALES ELECTRICAS CON FASES DISTINTAS. LAS SEÑALES ELECTRICAS PUEDEN TRABAJARSE EN UNA CAONEXION INTEGRADA Y PASAR A LA INDICACION. TODOS LOS ELEMENTOS, DESDE LOS SEMICONDUCTORES A LOS DETECTORES (+D',D',-D')ESTAN CONJUNTADOS EN EL SUSBSTRATO (S') EN FORMA DE UNA CONEXION OPTICA INTEGRADA.
