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.
