Abstract
Patente de Invenção: "SENSOR DE FRENTE DE ONDA PARA MENSURAçãO OBJETIVA DE UM SISTEMA óTICO E MéTODOS ASSOCIADOS". A presente invenção trata-se de um sensor de frente de onda que inclui um estágio de transmissão afocal para ampliar uma frente de onda que entra refletida a partir do plano fonte. Em uma aplicação exemplificativa, a retina do olho reflete um feixe de luz incidente na mesma para formar uma série de frentes de onda. Uma armação de lentículas é posicionada no plano de referência do estágio de transmissão afocal para receber a frente de onda ampliada. Ademais, se encontra a jusante posicionado um meio para refletir e reduzir a imagem do plano focal da armação de lentículas no plano de imagem final. A referida imagem reduzida serve então como um dado de entrada ao analisador, tal como uma câmera com dispositivo de carga acoplado (CCD).
