Abstract
PURPOSE: To readily obtain the necessary information during work, the evaluation, etc. after perfection by using a laser luminous flux turning device and a rotary camera rotating synchronously with this and photographying the locus of irregular reflection at the tunnel inside surface.
CONSTITUTION: A revolving shaft member 15 is fixed to a rotary comera 1 and a reflecting mirror 16 is mounted to its end. Laser luminous flux LB enters a reflecting mirror 16 through a reflecting mirror 18. These enable the rotation of the camera and luminous flux LB synchronously within parallel planes. In addition, the distance up to the wall surface is obtained by X=constant/x0 from the position of the (p) point which the irreguarly reflected light of the P point past the lens system 2 draws on a film 5. If with this constitution the camera is rotated by the specified angle, the (p) points corresponding to the respective continuous P points are obtained as a continuous curve. The length on the film shows angles and the shape of the tunnel inside surface may be drawn by obtaining the distances from the deviations in the rectangular direction from the centerline.
