Title: Laser interferometer for measuring length
Inventor: KODAMA KENICHI
IPC: G01B9/02
Filed: 1993-06-04
Abstract: PURPOSE:To prevent a length measurement error from being generated due to the rotation of a movable hermetic container by allowing reference beams to pass through a reference beam transmission member provided in one piece with the movable hermetic container. CONSTITUTION:A side surface part 4a of a movable hermetic container 4 is allowed to stick out upward and the stick-out part constitutes a reference beam transmission plate 4c. When the movable hermetic container 4 moves in synchronization with a traveling mirror 5, the distance in side surface parts 4a and 4b of the movable hermetic container 4 where a length measuring beam Bm passes changes if the movable hermetic container 4 rotates. Then, a reference beam Br also passes one part (a reference beam transmission plate 4c) of the side surface part 4a of the movable hermetic container 4 and the distance in the beam transmission plate 4c where the reference beam Br passes also changes. Assuming that the thickness of the side surface part 4a of the movable hermetic container 4 is uniform, it is entirely the same as the case of the length measuring beam Bm and the optical path length difference between the length measuring beam Bm and the reference beam Br does not change.
