Abstract

Two corner cubes are opposed to share one or two mirror surfaces in common thereby integrally forming two mirror groups, and driven to be reciprocatively rotated in a plane including two opposite edges thereof or a symmetry plane including an edge defined by the two common mirror surfaces, while a beam splitter is provided in front of the two corner cubes for reflecting a part of incident light and guiding the same to one of the corner cubes as well as transmitting the remaining part of the incident light and guiding the same to the other one of the corner cubes while causing interference between light components reflected from the corner cubes.
According to the present invention, a moving mechanism may simply cause reciprocative rotation movement about one center of rotation, and adjustment in assembling is extremely simple and easy to allow reduction in manufacturing cost.
A double corner cube member, which can be formed of the same material, is stable against disturbance such as vibration and temperature change.
When plane mirrors for forming the corner cubes are manufactured by machining such as cutting or grinding, it is possible to perform assembling and working in high accuracy.
