Abstract
aparelho de imageação tomográfica óptico e método de imageação para ele. um aparelho de imageação ajusta as direções de polarização dos feixes de irradiação (para uma grade de difração) correspondendo aos primeiro e segundo feixes, respectivamente, que têm diferentes direções de polarização (por exemplo, ajustando-se um ângulo relativo formado entre as extremidades emissoras de luz das respectivas fibras mantenedoras de polarização), de modo que as características espectrais dos feixes de irradiação da grade de difração coincidam entre si. em seguida, o apaelho de imageação adquire uma imagem tomográfica indicando informações de polarização para um objeto com base nos feixes (que vem da grade de difração, para dividir e difratar um feixe da unidade de ajuste) correspondendo aos primeiro e segundo feixes, respectivamente, que têm diferentes direções de polarização.
