| description | PROBLEM TO BE SOLVED: To provide a food inspection device capable of accurately determining a foreign matter by reducing a noise due to the optical non-uniformity of an object to be inspected.SOLUTION: A food inspection device 100 includes: a light source 1 for irradiating an object to be inspected with inspection light; an image receiver 2 for receiving light transmitted through the object to be inspected to generate image data; a first polarizer 4 arranged on an optical path between the light source 1 and the object to be inspected for linearly polarizing the inspection light; a second polarizer 5 arranged on an optical path between the object to be inspected and the image receiver 2 for linearly polarizing transmission light; and polarization direction control means capable of changing a relative angle made by the transmission axis of the first polarizer 4 and the transmission axis of the second polarizer 5. The food inspection device 100 is configured to image a first image having a small relative angle and a second image having a large relative angle by using the image receiver 2, and to detect a foreign matter existing in the object to be inspected by using the first image and the second image.SELECTED DRAWING: Figure 1
【課題】検査対象物の光学的不均一性等に起因するノイズを低減して、異物を精度良く判別できる食品検査装置を提供する。【解決手段】食品検査装置１００は、検査光を検査対象物に照射する光源１、検査対象物を透過した光を受光して画像データを生成する受像器２、光源１と検査対象物との間の光路上に配置され、検査光を直線偏光させる第１の偏光子４、検査対象物と受像器２との間の光路上に配置され、透過光を直線偏光させる第２の偏光子５、および第１の偏光子４の透過軸と第２の偏光子５の透過軸とのなす相対角を変更可能な偏光方向制御手段とを備えている。食品検査装置１００は、受像器２を用いて相対角が小さい第１画像と相対角が大きい第２画像を撮像すると共に、この第１画像と第２画像を利用して検査対象物中に存在する異物を検知する。【選択図】図１ |
