Title: Shape measuring instrument for body
Inventor: ITO GIICHI
IPC: G01B11/24
Filed: 1986-10-03
Abstract: PURPOSE:To find the shape of the surface of a body to be measured in a short time by sweeping the surface of the body with planar laser beams, detecting the movement of a bright line by plural photodetecting element arrays, and obtaining many measurement points in plural sequences by one sweep. CONSTITUTION:Signal light (forming planar beams light l) emitted by a laser beam source LD is reflected by a rotary mirror M which rotates and vibrates reciprocally and projected on the body J to be measured, so that bright lines Q and Q' sweep the body J. The bright lines are perpendicular to the sweeping direction. A photodetector R consists of a photodetection lens L and plural photodetecting element arrays (S0, S1...Sn-1) and detect images (q) and (q') of the bright lines Q and Q' on the surface of the body J, so that photodetecting elements corresponding to the (q) and (q') generate electric outputs. When the bright lines Q and Q' sweep the body J downward, (n) sequences of measurement values corresponding to the photodetecting element arrays are obtained.
