Abstract:
Provided is an optical measurement device configured so that a high-accuracy three-dimensional image can be obtained. An emission angle of a ray of light is changed in such a manner that the rotation frequencies of two motors configured to rotatably drive a first optical path changing unit and a second optical path changing unit is controlled. The ray of light is emitted to a front three-dimensional region, and reflected light is obtained. Then, calculation is made by a computer, and in this manner, three-dimensional data on a measurement target object is obtained. The amount (vibration amount) of axial backlash or play of a rotary mechanism, such as a motor shaft, along which the ray of light is emitted is measured in real time, and such a backlash or play amount is subtracted from a three-dimensional image obtained by the computer. Consequently, a high-accuracy three-dimensional image is obtained.

Claim (Index 7):
A method for revising the optical measurement device according to  claim 4 , wherein\n a revision block formed of, e.g., a flat plate is disposed at a front of the probe of the optical measurement device, when a ray of light is three-dimensionally emitted during rotation of the probe,\n an inter-target distance T is T=(D2\u2212L2), and \n a value Ls as Ls=(Ds\u2212T) is used as a reference value of the translucent reference plate, where for each point, a given true distance to the revision block is Ds, a pre-revised measurement value by the probe is D2, and a measured distance to the reference plate is L2.
