Abstract
An optical displacement meter that measures a cross-sectional profile of a workpiece, and includes: a light projecting/receiving module including a light projecting unit that emits slit light extending in an X direction, a light receiving lens that collects reflected light of the slit light reflected by the workpiece, and an imaging unit that receives light collected by the light receiving lens; a motor that integrally rotates the light projecting/receiving module; and a control unit that controls the motor to scan the slit light in a direction orthogonal to the X direction. A rotation angle is limited to prevent specularly reflected light reflected from a specular reflection surface from being captured by the imaging unit when the light projecting unit irradiates the workpiece having the specular reflection surface parallel to an X-Y plane extending in the X direction and a Y direction with the slit light.
