Abstract

UN SISTEMA PARA REDUCIR HOLOGRAMAS ESPURIOS EN UN CONJUNTO DE GRABACION DE HOLOGRAMAS QUE INCLUYE UN ELEMENTO ABSORBENTE, TRANSPARENTE, SOPORTADO SOBRE UN SUSTRATO. EL ELEMENTO TRANSPARENTE ESTA SITUADO PARA QUE ESTE RELACIONADO DIRECTAMENTE CON UN HAZ DE EXPOSICION. EL ELEMENTO TRANSPARENTE TIENE UN DESEQUILIBRIO DE HUMEDAD DURANTE UN TIEMPO DE EXPOSICION. POR CONSIGUIENTE, EL ELEMENTO TRANSPARENTE AUMENTA O DISMINUYE DE ESPESOR DEPENDIENDO DE UNA DIFERENCIA DE HUMEDAD ENTRE EL Y EL MEDIO AMBIENTE. A MEDIDA QUE CAMBIA EL ESPESOR, UN DESPLAZAMIENTO DE FASE EN LAS REFLEXIONES LUMINOSAS DENTRO DEL CONJUNTO DE GRABACION DESENFOCA LOS HOLOGRAMAS ESPURIOS MIENTRAS DEJA INTACTO EL HOLOGRAMA DESEADO.
