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 4):
The optical measurement device according to  claim 3 , comprising:\n a first pulse generation unit configured to generate at least one or more pulses in a single rotation according to a rotation angle of the first motor; a second pulse generation unit configured to generate at least one or more pulses in a single rotation according to a rotation angle of the second motor; and a control unit configured to adjust rotation speeds of the first and second motors based on the pulses from the first and second pulse generation units, wherein by rotation made such that a relationship between the rotation speed N1 of the first motor and the rotation speed N2 of the second motor satisfies N2=N1\u2212X [rotations/second], the ray of light is emitted forward from the first optical path changing unit at the rotation speed N1 [rotations/second], and an emission angle of the ray of light with respect to the rotation center is changed at a speed X [rounds/second].
