Abstract: Provided is an optical displacement meter capable of solving problems such as dustproof and safety at the time of an operation and acquiring profiles of a plurality of positions of a workpiece with high accuracy without providing a conveyor or a linear motion mechanism. An optical displacement meter includes a light projecting and receiving module that integrally holds a light projecting unit, a light collecting unit, and a capturing unit to have a Scheimpflug relationship, a motor that integrally rotates the light projecting and receiving module, a housing that stores the light projecting and receiving module, and a control unit that controls the motor, and rotates the light projecting and receiving module in a state where the Scheimpflug relationship is maintained inside the housing to scan the slit light in a direction orthogonal to an X direction.

Abstract: An influence of fretting wear is suppressed. An optical displacement meter 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 from a workpiece, and an imaging unit that receives light collected by the light receiving lens; a motor integrally rotating the light projecting/receiving module; a bearing supporting a rotation shaft of the light projecting/receiving module; and a control unit controlling the motor to rotate the light projecting/receiving module within a first angle range to be measured to scan the slit light in a direction orthogonal to the X direction. The bearing is rotated together with the light projecting/receiving module by the rotation of the motor to a second angle range not to be measured on the outer side of the first angle range.
