PURPOSE:To perform the detection suited for visual feeling with less space by obtaining a distributed light pattern equal and resembling to a distributed light pattern in a short distance by the use of an optical lens, and measuring and processing the luminous intensity of each point thereof. CONSTITUTION:The distributed light similarly reduced, for example, 10m distributed light is obtained on a plane installed with a photosensor array Sm by a headlamp HL and a condenser lens L. The photosensor array Sm detects the quantity of light of them positions on a straight line and the output thereof is inputted to a microcomputer MPU. The microcomputer MPU consists of a storage circuit MEM, an input-output circuit IO and a central processing unit CPU, calculates orientation by operation and displays the results thereof in a display panel DP. |
