PROBLEM TO BE SOLVED: To solve the problem that, in an imaging system which emits light and captures an image with return light, the image to be captured may be easily influenced by external light.SOLUTION: The imaging system comprises: a light source; a first circular polarizing filter for converting light from the light source into first circularly polarized light; a light emission part for emitting the first circularly polarized light that has been converted by the first circular polarizing filter, to an external space; a second circular polarizing filter for transmitting therethrough second circularly polarized light in a counter-rotating-direction of the first circularly polarized light, in light from the external space; and an imaging part for capturing an image with the light transmitted through the second circular polarizing filter in the light from the external space.SELECTED DRAWING: Figure 2
【課題】光を出射して戻り光により撮像する撮像システムにおいて、撮像される画像が外来光の影響を受けやすいこと。【解決手段】撮像システムは、光源と、光源からの光を第1円偏光に変換する第1円偏光フィルタと、第1円偏光フィルタによって変換された第1円偏光を外部空間に出射する光出射部と、外部空間からの光のうち、第1円偏光の回転方向の逆回りの第2円偏光を透過する第2円偏光フィルタと、外部空間からの光のうち第2円偏光フィルタを透過した光により撮像する撮像部とを備える。【選択図】図2
