Abstract

método; válvula de gravação óptica;e programa de computador incorporado em uma memória e legível por um computador para realizar ações direcionadas para transmitir luz de gravação. trata-se de método, dispositivo e programa de computador detalhados para modular luz de gravação. para uma pluralidade de locais de pixel de uma camada eletroóptica de uma válvula de gravação óptica e através de cada um de uma pluralidade de quadros consecutivos, um conjunto de bits de dados de pixel é modulado através de um primeiro e de um segundo períodos de largura de pulso do quadro. os primeiro e segundo períodos de largura de pulso e períodos de pulso adjacentes dos quadros seqúenciais são separados uns dos outros por um período com pulso desativado que é pelo menos igual a um tempo de resposta da camada eletro-óptica durante o qual nenhum bit é modulado. separadamente em cada quadro, luz de gravação é transmitida a partir de cada um da pluralidade de locais de pixel de acordo com os bits de dados de pixel modulados no quadro. em uma modalidade, o conjunto de bits de dados de pixel é modulado pela aplicação de uma tensão em um local de pixel da camada eletro-óptica em sincronismo com a iluminação de uma fonte de luz que ilumina aquele local de pixel.
