Abstract
An alignment interferometer telescope apparatus comprises a coherent laser source, a first beam splitter, a reference spherical mirror, a light source, first and second reticles, and a second beam splitter. At an interference location within the apparatus, a reference laser wave and a test laser wave are allowed to interfere to produce a combined laser wave.
Claims6
A method for a telescope, the method comprising:
- producing a coherent laser wave;
- splitting the coherent laser wave into a reference path laser wave and into a test path laser wave;
- transmitting the test path laser wave to an object outside the telescope;
- receiving the test path laser wave at an interference location within the telescope upon reflection from the object;
- reflecting the reference path laser wave to the interference location;
- combining the reference path laser wave and the test path laser wave to produce a combined laser wave;
- producing a light;
- projecting an image from a first reticle with the light;
- transmitting the projected image to the object;
- receiving the projected image at a second reticle;
- and
- superimposing the projected image with a reference image from the second reticle.
