Abstract

"ELEMENTO óPTICO COM MODULAçãO COMPLEXA COMPLETA DE FRENTES DE ONDA DE LUZ, E SEU PROCESSO DE OBTENçãO". A presente invenção refere-se a um elemento óptico que realiza a modulação complexa completa - de fase e amplitude, simultaneamente - de frentes de onda de luz. A modulação de fase é propiciada por alteração do caminho óptico (por exemplo por variação de espessura ou pela presença de relevos na superfície óptica) e a modulação de amplitude é propiciada por obstrução ao caminho da luz, (por exemplo refletindo, absorvendo, atenuando, bloqueando, polarizando ou variando a polarização da luz.
