Paper Abstract

Provided a coherently-illuminated extended object as well as a coherent point-source beacon, multiplexed digital holography grants both imaging and wavefront sensing functions for the purposes of atmospheric characterization. As such, this paper explores the tradespace between two multiplexed digital holography systems: one operating in the off-axis image plane recording geometry and the other operating in the off-axis pupil plane recording geometry. Via wave-optics simulations, we vary the signal-to-noise ratio and the sampling quotient for each recording geometry while assessing performance via several metrics including the field-estimated Strehl ratio. The performance for each recording geometry largely agrees with the theoretical results.
