Paper Abstract

The infrared imager currently in use at the National Optical Astronomy Observatories (NOAO) has been adapted for use as a two-dimensional infrared speckle camera operating at wavelengths of 1μm 5μm. Data have been obtained at the Kitt Peak National Observatory (KPNO) Mayall telescope (effective aperture ti 3.8m) for a number of different sources. Diffraction-limited images are presented for two objects, the "Red Rectangle" and NML Cygnus, using the Knox-Thompson algorithm to recover the Fourier phases. A comparison of phase-relaxation techniques applied to the integrated phase differences is presented using both the Hudgin method and successive over-relaxation.
