Abstract

1,175,998. Mirror mounts. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. July 21, 1967 [July 21, 1966], No.33762/67. Heading G2J. [Also in Division G1] A device for cyclicly modulating the length of the path taken by a beam F 1 comprises a pair of mirrors 21, 22 deflecting the beam F 1 to a prism assembly 23 movable by a cam 25 along a guide 24. The cam is symmetrical about the line X 1 X 2 and has a form: p = k# - p o for O < # < #.
