To provide a cleaning device that can efficiently remove a foreign matter adhering to a translucent body, an imaging unit equipped with the cleaning device, and a cleaning method.SOLUTION: A cleaning device 10 includes a protective cover 2, a vibrating body 12, a piezoelectric drive unit, and a signal processing circuit. When it is determined that a foreign matter has adhered to the surface of the protective cover 2, the signal processing circuit controls the piezoelectric drive unit such that the vibration of the protective cover 2 becomes a vibration acceleration of 1.5×105 m/s2. When it is determined that a foreign matter has adhered to the surface of the protective cover 2 even in a case in which the piezoelectric drive unit is controlled such that the vibration of the protective cover 2 becomes a predetermined vibration acceleration, the protective cover 2 is heated by a heating unit, and the piezoelectric drive unit is controlled such that the vibration of the protective cover 2 becomes a resonance frequency after the protective cover 2 has been heated.SELECTED DRAWING: Figure 1
【課題】本開示は、透光体に付着した異物を効率的に除去することができる洗浄装置、洗浄装置を備える撮像ユニット、および洗浄方法を提供する。【解決手段】洗浄装置10は、保護カバー2と、振動体12と、圧電駆動部と、信号処理回路と、を備える。信号処理回路は、保護カバー2の表面に異物が付着したと判断した場合、保護カバー2の振動が1.5×105m/s2の振動加速度となるように圧電駆動部を制御し、保護カバー2の振動が所定の振動加速度となるように前記駆動部を制御しても保護カバー2の表面に異物が付着したと判断した場合、加温部で保護カバー2を加温し、保護カバー2の加温後に、保護カバー2の振動が共振周波数となるように圧電駆動部を制御する。【選択図】図1
