Abstract
An optical displacement meter includes a light projecting unit that irradiates a workpiece with slit light, an image sensor that outputs a light receiving amount distribution of reflected light from the workpiece, a motor, a control unit that controls the motor, causes the slit light to scan, and exposes the image sensor while rotating the image sensor, and a rotation angle acquisition unit that acquires a reference angle corresponding to an exposure period of the image sensor. The control unit acquires a peak position in a V direction of the light receiving amount distribution during the exposure period, and estimates a representative angle at which the peak position is acquired based on the reference angle corresponding to the exposure period and a control condition of the image sensor or the motor, and calculates a height of the workpiece at the representative angle from the peak position.
