释义	echelon A form of interferometer consisting of a stack of glass plates arranged stepwise with a constant offset. It gives a high resolution and is used in spectroscopy to study hyperfine line structure. In the transmission echelon the plates are made equal in optical thickness to introduce a constant delay between adjacent parts of the wavefront. The reflecting echelon has the exposed steps metallized and acts like an exaggerated diffraction grating
