11. William Smith used Long Michelson interferometer observations of sources to do the same. 12. NPOI is a successful astronomical interferometer of the venerable and proven Michelson Interferometer design. 13. It is a variant of Michelson interferometer that can be installed on a microscope. 14. It is a variant of Michelson interferometer that can be installed on a conventional microscope. 15. The Michelson interferometer and the Mach-Zehnder interferometer are examples of amplitude-division systems. 16. The spectrometer is an adapted version of the classical Michelson interferometer using an optimized optical layout. 17. The Holometer will consist of two power-recycled Michelson interferometers , similar to the LIGO instruments. 18. Examples include the Michelson interferometer , the Twyman-Green interferometer, and the Mach-Zehnder interferometer. 19. Compared with Lyot filters, which use birefringent elements, Michelson interferometers have a relatively low temperature sensitivity. 20. The survey was produced using the Long Michelson Interferometer at the Old Rifle Range in Cambridge in 1950.
