PROBLEM TO BE SOLVED: To provide a detection device which can detect a subject at different wavelengths.SOLUTION: A detection device includes a wavelength filter that at least allows near infrared light to pass through the wavelength filter and does not allow visible light to pass therethrough, a fluorescent body that allows the near infrared light having passed through the wavelength filter to pass through the fluorescent body and emits fluorescence upon incidence of X-rays, and a semiconductor sensor that detects the near infrared light having passed through the fluorescent body and the fluorescence.COPYRIGHT: (C)2014,JPO&INPIT【課題】 異なる波長で被写体を検出できる検出装置を提供する。【解決手段】 検出装置は、少なくとも近赤外光を透過し且つ可視光を透過しない波長フィルタと、前記波長フィルタを透過した近赤外光を透過し、X線の入射に対しては蛍光を発生する蛍光体と、前記蛍光体を透過した近赤外光及び前記蛍光を検出する半導体センサとを有する。【選択図】 図1
