MIRROR ATTITUDE ADJUSTING METHOD AND MIRROR ATTITUDE DETECTING EQUIPMENT

摘要

PURPOSE: To reduce the time needed for adjustment work by immediately detecting the attitude of a mirror from the result of measurement of a pinhole image. CONSTITUTION: A mirror attitude detecting equipment is constituted of a pinhole board 10 and two sheets of detecting boards 11, 12. The position and the angle of a first curved surface mirror 3 are measured from a pinhole image on the first detecting board 11. The degree of deviation of the position and the angle of the first curved surface mirror 3 from the desired angle and position is detected, and the angle and the position of the first curved surface mirror 3 are adjusted by the difference. In the same way, the deviation of the position and the angle of the second curved surface mirror 4 is measured from a pinhole image on the second detecting boards 12. The angle and the position of the second curved surface mirror 4 are adjusted by the difference.
