Single-pixel scatter-plate microscopy

Opt Lett. 2021 May 15;46(10):2473-2476. doi: 10.1364/OL.420593.

Abstract

Based on the optical memory effect of scattered light, we developed a new single-pixel camera concept. The retrieved images contain both 3D and spectral information about the sample. A spatial light modulator (SLM) generates a random intensity modulation. The signal recorded by the single-pixel detector is cross correlated by the calculated point spread function (PSF) signals of the SLM to retrieve the image. In this publication, both simulations and experimental results are presented.
