摘要： PROBLEM TO BE SOLVED: To obtain a method for the discrimination of reflected light, which is precise, simple and practical. SOLUTION: A plurality of reflectors (retroreflecting bodies) whose positions are specified are arranged around a moving body 1. The beam of a semiconductor laser 11 is cast over the whole circumference from the moving body 1. The angle θ of rotation of a mirror which radiates a beam of light at a time when the reflected light of the beam is received by a light receiving element 32 is detected. Angle ranges θmin to θmax of the angle of rotation of the mirror which receives beams of reflected light from the reflectors by the light receiving element 32 are estimated. When the detected angle of rotation of the mirror is within the estimated ranges θmin to θmax of the angle of rotation, the beams of reflected light are recognized as beams of reflected light from the reflectors. By this method, a noise of the reflectors can be discriminated from a noise of other objects (a regular reflecting body such as a window, a metal frame, a pipe or the like), a disturbance noise can be removed in a laser guidance system, and it is possible to prevent the erroneous detection of the positions due to the noise.

摘要： PURPOSE:To eliminate the need for large-scale facilities by fitting a reflecting mirror in front of the center intersection part of a cross-shaped leaf spring and moving rods fitted to the rear surfaces of length intermediate parts of the respective arms of the cross-shaped leaf spring in their lengthwise directions. CONSTITUTION:A command signal outputted by a main controller 4 is sent to a driving device 14 through a D/A converter 5 and a driving control circuit 6 to move the rods 13 axially. Consequently, the plane mirror 12 for laser light reflection is rotated around an X axis and a Y axis to display an image P on a projection body 2. The angles of rotation of the plane mirror 12 around the X and Y axes are detected by a detecting device 24, whose detection signal is sent to the driving control circuit 6. Then the driving device 14 is brought under the feedback control of the driving control circuit 6. Thus, light which is incident on the reflecting mirror 12 is guided on a photodetection surface in optical two-dimensional directions and the image P is easily drawn on the projection body 2.
