Claims

[Scope of utility model registration request]

A light emitting system including a laser light source and a mechanism for changing the irradiation angle of the laser light around a fixed axis; and a light receiving system including an electric zoom, a light receiving surface, and a mechanism for changing the light receiving angle around a fixed axis. , a three-dimensional shape consisting of a mechanism for displacing the measurement system in a specific linear direction, which is installed with the light receiving system and the light receiving system separated by a certain distance, and a mechanism for rotationally driving the object to be measured around a certain axis. In this measurement device, the directions of the three rotational axes and the displacement of the measurement system are configured to be parallel to each other, and during measurement, the reflected light from the object is detected at a specific position on the light receiving surface, which is equipped with a mechanism to increase the resolution. A non-contact measurement device for three-dimensional objects that receives light.
