To provide an abnormality detector with which it is possible to detect abnormality early.SOLUTION: An abnormality detector 1 detects the abnormal deformation of a measurement object that is a rigid body. The abnormality detector 1 comprises: a first light emitting unit 11 for radiating a laser beam L1 and installed in a first portion of the measurement object; a first light receiving unit 12 installed in a second portion of the measurement object which is apart from the first position and having a plurality of divided light receiving regions for receiving the laser beam radiated from the first light emitting unit 11; and a determination unit 30 for determining, on the basis of the output of the first light receiving unit 12, whether the measurement object is deformed.SELECTED DRAWING: Figure 1
【課題】早期に異常を検出することが可能な異常検出装置を提供する。【解決手段】異常検出装置1は、剛体である測定対象物の異常変形を検出する。異常検出装置1は、測定対象物の第1部分に設置され、レーザ光L1を放射する第1発光部11と、測定対象物の第1部分とは離れた第2部分に設置され、第1発光部11から放射されたレーザ光を受光する複数に分割された受光領域を有する第1受光部12と、第1受光部12の出力に基づいて測定対象物の変形の有無を判定する判定部30とを備える。【選択図】図1
