Abstract

ES POSIBLE CONSTRUIR UN DISPOSITIVO PARA MEDIR UNA SUPERFICIE ESFERICA, EN PARTICULAR LA CORNEA DEL OJO HUMANO, DE TAMAÑO REDUCIDO Y QUE NO PROVOQUE ELEVACION DE LA TEMPERATURA DURANTE SU USO, PUES LAS FUENTES LUMINOSAS QUE PRODUCEN UN MOTIVO SOBRE LA MENCIONADA SUPERFICIE CONSISTEN EN UN SISTEMA DE DIODOS FOTOEMISORES APOYADOS POR UN REFLECTOR MONTADO DETRAS DE UNA MASCARA QUE FORMA EL MOTIVO. EL DISPOSITIVO PUEDE TAMBIEN UTILIZARSE PARA DETERMINAR LA REACCION DE LA PUPILA AL DESLUMBRAMIENTO SI SE REFLEJA UNA FUENTE LUMINOSA EXTERNA EN LA TRAYECTORIA DEL HAZ.
