Improved heterodyne mixing efficiency and signal-to-noise ratio with an array of hexagonal detectors.
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-front misalignment between the signal and the local oscillator wave fronts for both pixel geometries.
