Abstract

The triple correlation algorithm employing a minimum of computation is evaluated as a candidate process for near-real-time, quick-look, stellar image reconstruction at the telescope. Computational efficiency is gained by exploiting the binary nature of the photon-list images and by using a small number of high SNR bispectrum subplanes. When compared to the Knox-Thompson algorithm extended to 2, 4 and 6 subplanes, the fidelity of reconstruction by the TC process is better and less object dependent, even in the minimum-computation case of 2 planes.
