Abstract

"DISPOSITIVO DE CORREçãO ELETRôNICA DAS DISTORçõES óPTICAS DE UMA VISUALIZAçãO COLIMATADA OBTIDA A PARTIR DE UM VISOR MATRICIAL". A invenção refere-se a um dispositivo de correção eletrônica das distorções ópticas de uma óptica de colimação e de superposição de uma visualização colimatada no caso de o visor ser do tipo matricial. O princípio da invenção é de realizar essas correções ao nível do visor, associando a cada pixel do visor o mesmo número de pixels de cada imagem-fonte a visualizar, os endereços dos pixels das imagens-fontes sendo calculados a partir dos endereços dos pixels do visor, aplicando-lhes a função de distorção da óptica. O cálculo dos endereços e dos valores fotométricos dos pixels do visor é feito em uma unidade de cálculo que compreende notadamente uma unidade de cálculo de endereços e uma unidade de interpolação. A invenção aplica-se essencialmente aos dispositivos de visualização ditos da Altura dos olhos ou de casco utilizados sobre aeronaves civis e militares que têm como visor dispositivos matriciais notadamente com cristais líquidos. O dispositivo se aplica tanto aos visores monocromáticos quanto aos visores coloridos.
