Bath Interferometer (common Path)
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 (typically a He Ne laser). Bath also published an article about his favorite variation in June of 1973. Before the patent there was a functionally identical Right Angle Bath interferometer described and published in the journal Optical Engineering (the article was received by the journal on July 23, 1973).

Common-path Interferometer
A common-path interferometer is a class of interferometers in which the reference beam and sample beams travel along the same path. Examples include the Sagnac interferometer, Zernike phase-contrast interferometer, and the point diffraction interferometer. A common-path interferometer is generally more robust to environmental vibrations than a "double-path interferometer" such as the Michelson interferometer or the Mach–Zehnder interferometer. Although travelling along the same path, the reference and sample beams may travel along opposite directions, or they may travel along the same direction but with the same or different polarization. Double-path interferometers are highly sensitive to phase shifts or length changes between the reference and sample arms. Because of this, double-path interferometers have found wide use in science and industry for the measurement of small displacements, refractive-index changes, surface irregularities and the like. There are applications, howeve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
