The imaging accuracy is improved while using a simple optical system. The imaging device (1) transmits non-transmitted light that has not been transmitted through the imaging target (5) and transmitted through the imaging target (5) without being scattered among the infrared polarized light emitted from the light source (2). A polarizing filter (3) that blocks light and transmits transmitted light scattered and transmitted through the inside of the imaging target (5), and receives light that has passed through the polarizing filter (3) and images the imaging target (5). An image sensor (4).簡便な光学系を用いながら撮像精度を向上させる。撮像装置（１）は、光源（２）から照射された赤外線の偏光のうち、撮像対象（５）を透過していない非透過光、及び撮像対象（５）内部を散乱せずに透過した透過光を遮断し、撮像対象（５）内部を散乱して透過した透過光を透過させる偏光フィルタ（３）と、偏光フィルタ（３）を透過した光を受光して撮像対象（５）を撮像する撮像素子（４）とを備える。
