Offset detection apparatus and flying object guiding system using the apparatus |
摘要 |
A light wave guiding apparatus comprising an offset detector for detecting an offset from a predetermined axis is disclosed. A laser beam irradiator (11) irradiates a laser beam (13) having a maximum irradiation intensity in a predetermined orientation and the irradiation intensity decreasing progressively with the increase in the distance away from the orientation while being conically inclined from a predetermined axis (12). A photo-detector (15) is located in an area (14) irradiated by the laser beam (13) and outputs a received light signal S corresponding to the irradiation intensity. A memory unit (17) stores the relation between the amount of offset of the photo-detector (15) from the predetermined axis and the received light signal S. The received light signal S of the photo-detector (15) is compared with the data stored in the memory unit (17) and the offset amount of the photo-detector (15) is detected. <IMAGE> |
