To provide a detection device capable of accurately detecting an object.SOLUTION: A detection device includes: a first irradiation unit applying first electromagnetic waves including a first polarization component to an object area; a second irradiation unit applying second electromagnetic waves not including the first polarization component to an object area with an incidence angle differing from that of first electromagnetic waves; a first detection unit that is disposed in a position opposing the first irradiation unit while sandwiching an object area and can detect only electromagnetic waves of the first polarization component; a second detection unit capable of detecting second electromagnetic waves reflected in the object area; and an image generation unit generating a two-dimensional image of an object existing within an object area on the basis of detection results of first and second electromagnetic waves by the first and second detection units.SELECTED DRAWING: Figure 1 【課題】正確に物体を検出することが可能な検出装置を提供する。【解決手段】第１の偏波成分を含む第１の電磁波を対象領域に照射する第１の照射部と、第１の偏波成分を含まない第２の電磁波を第１の電磁波とは異なる入射角で対象領域に照射する第２の照射部と、対象領域を挟んで第１の照射部に対向する位置に配置され、第１の偏波成分の電磁波のみを検出可能な第１の検出部と、対象領域において反射された第２の電磁波を検出可能な第２の検出部と、第１及び第２の検出部による第１及び第２の電磁波の検出結果に基づいて、対象領域内に存在する対象物の２次元画像を生成する画像生成部と、を有する。【選択図】図１
