Title: Optical path length adjusting device
Inventor: FRIEDRICH FERCHER
IPC: G01B11/00
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To easily change optical path length at high speed and to introduce zero selection at any time concerning the dispersibility in the optical path length by reflecting a light beam by a reflection mirror through a double mirror type optical path length adjusting device consisting of two flat mirrors juxtaposed in parallel with each other and rotating around a common shaft. SOLUTION: The light beam 1 collides with a double mirror consisting of plane mirrors 4 and 4' first. The light beam 1 is reflected from the mirror 4 to the mirror 4', and then advances in the same advancing direction as an original advancing direction and reaches the reflection mirror 7. The two mirrors 4 and 4' forming the double mirror are fixed so that they may be parallel with each other on a rotary disk. The disk 5 is rotated around the rotary shaft 6 and the mirrors 4 and 4' are also rotated with the rotation of the disk 5. Since the mirrors 4 and 4' are parallel with each other, the light beam 1 advances in parallel with the original advancing direction and collides with the mirror 7 when it goes out from this system.  The light beam 1 is reflected and advances in an opposite direction to the original advancing direction as the light beam 1' and goes away from the double mirror system.
