Scientific paper

Two techniques of high resolution infrared imaging have been studied concurrently. They are: (1) diffraction limited imaging (which compensates for atmospheric effects using speckle interferometry); and (2) infrared baseline interferometer imaging (which attains higher resolution using a two-telescope system). In the former, an infrared speckle imaging system with a 1.5 m diameter telescope has been developed. The diffraction limited imaging technique was verified by observations of a double star Alpha Gem and other objects. In the latter, some fundamental technologies such as infrared heterodyne detection, correlation and interference have been studied on the basis of an indoor experiment.
