Image restoration through thin turbid layers by correlation with a known object

Opt Express. 2013 May 20;21(10):12539-45. doi: 10.1364/OE.21.012539.

Abstract

A method to recover the image of an object behind thin turbid layers is developed by wavefront shaping technique. The optimized wavefront is generated by modulating the scattering light of a known object with a spatial light modulator. A Pearson Correlation Coefficient is introduced as a cost function for the optimization. A beam scanning method based on optical memory effect is proposed to further enlarge the Field-of-View (FOV). The experimental results show good fidelity and large FOV of the recovered image.
