Abstract
A device for joining light waves by interferometric focusing optics and a small reflector with a cylindrical or spherical surface, which is positioned in the aperture of the object imaging optics so that the reference wave is reflected towards the picture detector and covers this. An auxiliary device comprising one or more reflecting surfaces may be positioned in the path of the beam behind the reflector so that the reference wave can be coarsely adjusted toward the reflector. In the extension of the path of the reference wave from the mirror via the lens to the reflector, a viewing screen may be positioned such that one by means of the naked eye can do coarse adjustment of the reference wave which focuses on the reflector.
Claims8
A device for joining an object wave and a reference wave for interferometric analysis, where the object wave passes through an aperture before reaching a picture detector, comprising:
- object wave imaging optics having an imaging aperture for imaging said object wave;
- and
- a reflector having a convex reflective surface positioned in the path of said object wave in said imaging aperture to reflect said reference wave so as to cover said picture element, said reflector being smaller than said imaging aperture.
