摘要：

An array of hexagonal pixel geometries is considered and its improvement in the mixing efficiency as well as the signal-to-noise ratio is compared with an equal-area array of square pixel detectors. We also consider the phase-fron; misalignment between the signal and the local oscillator wave fronts for both pixel geometries. (C) 1997 Optical Society of America.
