Reconstruction of multispectral image cubes from multiple-telescope array Fourier transform imaging spectrometer

Abstract

Multiple-telescope arrays can function as Fourier transform imaging spectrometers, using the subaperture path-delay elements. However, the resulting spectral images are missing low spatial-frequency content. Reconstruction results are presented for a cube of simulated data using a nonlinear derivative-based sharpness metric that is designed for specific types of imagery.
