Practical considerations for high-fidelity wavefront shaping experiments

Year: 2024

Type: article

Abstract: Wavefront shaping (WFS) is a technique for directing light through turbid media. The theoretical aspects of WFS are well understood, and under near-ideal experimental conditions, accurate predictions for the expected signal enhancement can be given. In practice, however, there are many experimental factors that negatively affect the outcome of the experiment. Here, we present a comprehensive overview of these experimental factors, including the effect of sample scattering properties, noise, and response of the spatial light modulator. We present simple means to identify experimental imperfections and to minimize their negative effect on the outcome of the experiment. This paper is accompanied by Python code for automatically quantifying experimental problems using the OpenWFS framework for running and simulating WFS experiments.
