Single-shot blind deconvolution with coded aperture

TL;DR

This paper introduces a novel single-shot blind deconvolution technique using a coded aperture to simultaneously estimate objects and turbulence-induced point spread functions from a single image.

Contribution

It proposes a new method that leverages a coded aperture as support constraints to enable blind deconvolution of turbulence effects in a single shot.

Findings

Successful recovery of point sources under severe turbulence

Demonstrated effectiveness through simulation and experimental results

Estimation of both object and PSF from a single image

Abstract

In this paper, we present a method for single-shot blind deconvolution incorporating a coded aperture (CA). In this method, we utilize the CA, inserted on the pupil plane, as support constraints in blind deconvolution. Not only an object but also a point spread function of turbulence are estimated from a single captured image by a reconstruction algorithm with the CA support. The proposed method is demonstrated by a simulation and an experiment in which point sources are recovered under severe turbulence.
