Bath interferometer (common path)
text:
Karl-Ludwig Bath patented 5 designs of common path interferometers in 1973. Bath interferometers can be used to test telescope mirrors of any size. A Common path interferometer has the test and reference beams traveling over effectively the same path which has the advantage that you can use an inexpensive semiconducting laser pointer with low coherence versus other interferometers which need a high coherence laser. Bath also published an article about his favorite variation in June of 1973. Bef
