Abstract

SE DESCRIBE UN ESCANER DE HAZ OPTICO QUE INCORPORA UNA RED DE ELEMENTOS DE DEFLEXION DE HAZ COMUNMENTE CONTROLADOS PARA DIRIGIR UN HAZ OPTICO INCIDENTE SOBRE LA RED. LOS ELEMENTOS DE DIRECCION DE HAZ ESTAN DISPUESTOS EN LA RED COMO ELEMENTOS INDIVIDUALMENTE CONTROLADOS Y LA DEFLEXION DEL HAZ ES REALIZADA AJUSTANDO LA INCLINACION DE FASE Y EL DESFASE DE CADA ELEMENTO DE ACUERDO CON UN CALCULO QUE ELIMINA UN DESFASE DE MODULO 2 DE LA POSICION REQUERIDA CON RELACION A UNA SUPERFICIE PLANA. ESTOS ELEMENTOS DE DEFLEXION DE HAZ, TALES COMO DEFLECTORES DE HAZ DE CRISTAL LIQUIDO, ELIGIENDO UN ESQUEMA DE EXCITACION QUE REPRESENTA A UNA RED FLAMEADA O A UNA RED DE PISTON PLANO. EL FUNCIONAMIENTO PUEDE SER DISEÑADO PARA UN AMPLIO MARGEN DE LONGITUDES DE ONDA DE LUZ Y EL SISTEMA PUEDE ACOMODAR EFICAZMENTE UNA COMBINACION DE LAS TECNICAS DE FLAMEADO Y DE PISTON PLANO PARA OBTENER CARACTERISTICAS DE DEFLEXION DE HAZ QUE NO PODRIAN LOGRARSE DE OTRO MODO MEDIANTE EL USO EXCLUSIVO DE CADA TECNICA INDIVIDUAL.
