Abstract
We describe results from a program of speckle interferometry with two- dimensional infrared array detectors. Analysis of observations of eta Carinae made with a 58 x 62 InSb detector are discussed. The data have been analyzed with both the Labeyrie autocorrelation method, a deconv olution of shift-and-add data, and a phase restoration process. Develo pment of a new camera based on a much lower noise HgCdTe detector will lead to a significant improvement in limiting magnitude for IR speckl e interferometry.
