摘要： An angle-sensitive interferometer includes a first beam splitter for splitting a beam of coherent radiation into two portions and a second beam splitter for recombining the two beam portions to produce an interference pattern. It also includes reflecting mirrors and lenses for recombining the two beam segments in such a manner that an angle of deviation in the incident beam results in the recombined beams diverging from the interferometer axis to create a wedge angle. A corner cube reflector, cat's eye reflector, or a telescope with either convex lenses or concave mirrors are used for this purpose. The invention also includes a mirror in one of the beam portion paths to reflect it out of alignment with that beam portion path emerging from the first beam splitter so that the second beam splitter where the beam portions are recombined does not produce feed back into the radiation source. A quadrant diode is used to detect asymmetrical changes of intensity in the fringe pattern indicative of angle change of the incident beam. Apparatus for detecting, measuring, and controlling beam angles are also included.

摘要： Method and apparatus for mode coupling a light beam into an optical cavity having a cavity axis, effect reflection of light of that beam with a mirror along a geometric ray originating laterally of the cavity axis. The mirror is rigidly interconnected with the cavity and is adjusted until the geometric ray coincides with the light beam. That geometric ray is retained in space while moving the optical cavity so that the cavity axis moves translatorily relative to the retained geometric ray, until the cavity axis coincides with the retained geometric ray and thereby with the light beam. Where an optical cavity is located in an oven, first temperature variations of a wall of that oven and second temperature variations of the cavity are sensed, and energization of the oven is controlled more rapidly in response to these first temperature variations, than in response to those second temperature variations.
