Large Holographically Corrected Imaging and Nulling Interferometers
Abstract
Presented here is a method for the correction of large, inexpensive sparse telescope arrays over a narrow bandwidth. A hologram is created of the distributed primary which is capable of correcting for thousands of waves of random and geometrical errors while simultaneously compensating for phasing errors. Experimental results are presented that demonstrate the application of this technique to meter-class, six-segment imaging interferometers as well as a two-mirror nulling interferometer.
