摘要 | Provided is an imaging device whereby imaging accuracy can be improved while cost and device size are suppressed. An imaging device (1) that comprises: a light source (2) that is a semiconductor laser that emits infrared light on an imaging target (5); a polarizing filter (3) that blocks light reflected from the surface of the imaging target (5) and transmits light reflected from the inside of the imaging target (5); and an imaging element (4) that receives the light that has been transmitted through the polarizing filter (3) and captures an image of the imaging target (5). |
其他摘要 | 提供一种成像装置,由此可以在抑制成本和装置尺寸的同时提高成像精度。一种成像装置(1),包括:光源(2),其是在成像目标(5)上发射红外光的半导体激光器;偏振滤光器(3),其阻挡从成像目标(5)的表面反射的光并透射从成像目标(5)的内部反射的光;和成像元件(4),其接收已经透过偏振滤光器(3)的光并捕获成像目标(5)的图像。 |
