Abstract
In a case where displacement is measured by swinging a light projecting and receiving system, a height image and a received light image can be output. An optical displacement meter includes a light projecting and receiving module, a motor that swings the light projecting and receiving module, a motor control unit that controls the motor, and swings the light projecting and receiving module to scan slit light, a rotation angle acquisition unit that acquires a rotation angle by the motor, a signal processing unit that calculates UV coordinates based on a light reception amount distribution output by an image sensor and converts the UV coordinates and the rotation angle into XYZ coordinates based on a predetermined conversion condition, and a height image output unit that outputs a height image indicating a height of a workpiece on an XY plane based on the XYZ coordinates.
