Optical interferometer

The optical interferometer in which the incident light beam 3 is branched into 2 optical paths of the reflection light and the transmission light which cross at right angle with each other by the beam splitter 4 , and on each optical path, the reflection light is totally reflected by the first refle...

Zusammenfassung:The optical interferometer in which the incident light beam 3 is branched into 2 optical paths of the reflection light and the transmission light which cross at right angle with each other by the beam splitter 4 , and on each optical path, the reflection light is totally reflected by the first reflection unit 5 , and the transmission light is totally reflected by the second reflection unit 6 , and the reflection lights by both reflection units 5 and 6 are wave-combined again by the beam splitter 4 , and received by the light receiver 7 . The beam splitter 4 by which the incident light beam is wave-separated and wave-combined, is arranged with a little inclination from the vertical to the incident light beam.
