Description

[Brief explanation of drawings]

Figures 1A, B, and C are a front view, a plan view, and a perspective view showing the main parts of the embodiment of this invention, respectively;
The figure is a side view of a conventional biological cross-section display measurement device, and FIG. 3 is an explanation of the correspondence between the light-receiving point on the light-receiving surface of the detector and the measurement point of the object in the measurement device of FIG. 2. FIG. 4 is a block diagram of the electronic circuit section of the measuring device of FIG. 2, and FIG. 5 is a signal waveform diagram of each part of the block diagram of FIG. 4.

Claims (1)

[Claims for Utility Model Registration] A light emitting source that irradiates light waves toward a plurality of positions on the reference axis of an object to be measured, which is positioned with the reference axis as the axis, is a rotating surface with the reference axis as the axis. the object to be measured and the light emitting source are mounted so as to be relatively rotatable around the reference axis, and the light emitting source rotates in response to the irradiation of light waves to the plurality of positions. located on a line substantially parallel to the reference axis on the surface, the reflected light from the irradiation position of the object to be measured is received and detected by a detector, and based on the detection output of this detector, the A three-dimensional surface shape measuring device, wherein a distance to an irradiation position on a surface of a measured object is measured, and the detector is disposed offset from the parallel line in the relative rotation direction.
