Demonstration of multi-plane sharpness metric maximization on motion-compensated, multi-wavelength 3D digital holographic field data

Abstract

This Letter examines sharpness metric maximization methods on 3D images obtained at Table Mountain, Colorado. We employ multi-wavelength 3D imaging with digital holography and a pilot tone to obtain the aberrated images and use sharpness metric maximization to correct the aberrated images with both pupil-plane and multi-plane corrections. Image quality improves when sharpness metric maximization is used and particularly with multi-plane correction.
