Michelson wide-field stellar interferometry: principles and experimental verification

Not Accessible

Your library or personal account may give you access

Abstract

A new interferometric technique for Michelson wide-field interferometry is presented that consists of a Michelson pupil–plane combination scheme in which a wide field of view can be achieved in one shot. This technique uses a stair-shaped mirror in the intermediate image plane of each telescope in the array, allowing for simultaneous correction of the differential delay for the on-axis and off-axis image positions. Experimental results in a laboratory setup show that it is possible to recover the fringes of on-axis and off-axis stars with an angular separation of 1 arc min simultaneously and with a similar contrast. This new technique represents a considerable extension of the field of view of an interferometer without the need for extra observation time.
