Scientific paper

The authors report the first reconstruction of a true diffraction-limited image of the central object HD 97950 AB in NGC 3603. The image has been reconstructed by a 4-dimensional version of speckle masking (triple correlation processing). Speckle masking is a solution of the phase problem in speckle interferometry. The reconstructed image shows that HD 97950 AB consists of 4 stars (V-magnitudes 11.7, 11.7, 11.7 and 12.2; separations relative to A1: 0.78arcsec, 0.37arcsec and 0.34arcsec).
