Improved heterodyne mixing efficiency and signal-to-noise ratio with an array of hexagonal detectors

Not Accessible

Your library or personal account may give you access

Abstract

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.
