Abstract

sistema de projeção e método de acionar um sistema de projeção com mapeamento de campo. um sistema de projeção inclui uma fonte de luz configurada para emitir uma luz em resposta a dados de imagem; um modulador de luz de fase configurado para receber a luz a partir da fonte de luz e aplicar uma modulação de fase espacialmente variável sobre a luz, desse modo para dirigir a luz e gerar uma luz de projeção; e um controlador configurado para controlar a fonte de luz, controlar o modulador de luz de fase, e iterativamente para cada de uma pluralidade de subquadros em um quadro dos dados de imagem; determinar um campo de reconstrução, mapear o campo de reconstrução para um campo de modulação, escalonar uma amplitude do campo de modulação, mapear o campo de modulação para um campo de reconstrução de iteração subsequente e fornecer um sinal de controle de fase com base no campo de modulação para o modulador de luz de fase.
