Abstract
The technique of probability imaging is applied to the bright, well resolved, infrared binary star ζ Aqr. It is shown how the second probability density function (pdf) contains all pertinent information to reconstruct the binary system with no ambiguity. Relations between the second pdf and other techniques (speckle masking technique and fork algorithm) are briefly indicated. An analysis of the behaviour of the second pdf under additive signal-independent nose is undertaken. As expected from the general theory of signal processing, the second pdf of the noise is found to blur the second pdf of the signal by means of a convolution relation.
