| description | To provide a pin hole detection device that can improve detection accuracy of pin holes.SOLUTION: In a pin hole detection device 10, a detector 24 detecting pin holes 110 generated in an examined object 100 includes a plurality of optical fibers 30 propagating light transmitting the examined object 100. The plurality of optical fibers 30 is arranged side by side facing a light source 20. When a maximum detectable angle allowing for detecting the pin hole 110 with respect to an optical axis of the light source 20 is θ, a maximum incidence angle of the light the optical fiber 30 can propagate with respect to the optical axis of the light source 20 is set within a range of θ+0° to θ+5°.SELECTED DRAWING: Figure 1
【課題】ピンホールの検出精度を向上可能なピンホール検出装置を提供する。【解決手段】ピンホール検出装置１０において、被検査対象物１００に生じたピンホール１１０を検出する検出器２４は、被検査対象物１００を透過した光を伝播する複数の光学繊維３０を備える。複数の光学繊維３０は、光源２０に対向して並んで配置される。光源２０の光軸に対するピンホール１１０を検出可能な最大検出可能角度をθとすると、光源２０の光軸に対する光学繊維３０が伝播可能な光の最大入射角は、θ+０°～θ+５°の範囲に設定される。【選択図】図１ |
