Optical-axis aligning apparatus
专利汇可以提供Optical-axis aligning apparatus专利检索，专利查询，专利分析的服务。并且PURPOSE: To perform highly accurate optical-axis in a short time with less effort by monitoring and photographing the image of the light beam from a light emitting element and the image of an optical element, and driving and controlling an automatic stage for the light emitting element or the optical element.
CONSTITUTION: A light emitting element A and an optical element B are attached to holders 2 and 4 for an automatic light emitting element stage 1 and an automatic optical element stage 3. An automatic stage 8 for image sensing part drives and controls a TV camera 7 to an image sensing part drives and controls a TV camera 7 to an image sensing position P1 close to the stage 3 shown by a virtual line 7a. Even if the optical axis l2' of the element B is deviated from a reference optical axis l0, a light beam LB from the element A enters into the field of view of the camera 7. A microcomputer 6 receives the image data with regard to the light beam image and the projected image of the optical element from the camera 7 at the position P1. The stages 1 and 3 are driven and controlled based on the data. The optical axis is aligned so that the light beam LB is aligned with the reference optical axis l
0 of the camera 7. The stages 1 and 3 are driven and controlled at an image sensing position P2, and the alignement is securely performed.
