Long Wave Infrared Wavefront Reconstruction Through Complex Media

Abstract

A novel broadband infrared (IR) speckle imaging system with a thin scatterer and an uncooled microbolometric camera is employed to encode wavefront phase variations as local speckle deformations. The phase reconstruction from speckle shifts using a fast diffeomorphic algorithm ultimately demonstrates IR wavefront reconstruction through complex media.
