Stellar coronagraphy: two mono-axial configurations for the Achromatic Interfero Coronagraph

摘要

The standard AIC (Achromatic Interfero Coronagraph) has a "coude" geometry (the output beam leaves at right angle from the input beam) Thus, some extra optical parts are required to fit such a device within the optical train between a telescope and its IR camera To avoid this drawback, we present two mono-axial variants of the AIC
