in Fig. 13.16 are replaced by diffraction gratings, with each tilted with respect to
the axial ray incident upon it. This type of interferometer produces a Fizeau
fringe pattern at the detector. For a discussion of its features the reader should
consult the paper by Harlander and Roesler (1990).

CONCLUDING REMARKS
The dispersive devices discussed in this chapter range from the simple prism
to elegant interferometric devices such as the Fabry-Perot and Michelson spectro-
meters. Most of
the
discussion, however, is given to diffraction gratings and their
dispersive characteristics. This emphasis o
