Wide-angle Mach-Zehnder interferometer for monochromatically selective photography
Abstract
The paper describes an interferometer intended for use with a telescope to photograph the sodium D emission in the vicinity of Io and Jupiter. The principle of operation is to overcome severe scattered light contamination by localizing high-order interference fringes in the focal plane; the white scattered light in the area will then appear just as on an ordinary photograph, while the D emission becomes distinctively encoded as finely spaced fringes.
