Gault, W.A., Johnston, S.F. and Kendall, D.J.W. (1985) Optimization of a field-widened Michelson interferometer. Applied Optics, 24(11), pp. 1604-1608. (doi:10.1364/AO.24.001604)




This paper considers the optical design of a wide-angle fixed-path Michelson interferometer consisting of two arm glasses and an air gap. It is shown that this configuration can be optimized to give (a) extra large fringes (over 50° in diameter) over a range of wavelength, (b) a path difference nearly independent of wavelength, or (c) a path difference specified differently at two different wavelengths for observing a pair of doublets. Specific examples refer to the airglow wavelengths of 557.7, 630.0, 732.0 nm and others, and to a path difference of 4.5 cm. The properties of different glass combinations are discussed.
