Abstract

EXPLORADOR DE RAYO LASER QUE COMPRENDE UNA VENTANA DE EXPLORACION (4) A TRAVES DE LA CUAL SE EMITEN LOS RAYOS DE EXPLORACION, UN CONJUNTO DE CAPAS DE REGISTRO POR HOLOGRAMA (41, 42) QUE CONSTITUYEN LA VENTANA DE EXPLORACION, Y UN SISTEMA OPTICO PARA HACER INCIDIR UN RAYO LASER SOBRE LAS CAPAS DE REGISTRO HOLOGRAFICO DE UNA MANERA TAL QUE LAS TRAZAS DEL RAYO LASER EXPLOREN CADA CORTE DE CAPA HOLOGRAFICA PRODUCIDO CON LAS OTRAS DE LA VENTANA DE EXPLORACION. ESTE EXPLORADOR DE RAYO LASER ES MAS COMPACTO QUE LOS EXPLORADORES DE RAYO LASER CONVENCIONALES.
