Abstract

"DISPOSITIVO E MéTODO PARA MANIPULAçãO DE RESPOSTA TéRMICA EM UM MODULADOR". Mediante variação do espaçamento entre duas superfícies, uma das quais é disposta em frente da outra, um modulador interferométrico cria seletivamente interferência construtiva e/ou destrutiva entre ondas de luz refletoras das duas superfícies. O espaçamento desejado pode ser atingido pela deformação de uma ou ambas as superfícies. Um elemento de aquecimento associado a uma superfície particular causa a deformação pelo aquecimento do material que forma uma ou ambas as superfícies. Mediante variação da quantidade de calor aplicada, a quantidade de deformação é variada, permitindo assim que a distância entre as superfícies seja controlada e criando assim interferência construtiva e/ou destrutiva conforme desejado.
