Abstract

Quantitative phase imaging (QPI) techniques require multiple measurements to obtain the refractive index (RI) distribution of a sample. Here, we present a single-shot RI imaging method using spectral multiplexing and optical transfer function reshaping. In the present method, we simultaneously measure three intensity images of a sample with three optimized illumination patterns. Deconvolution of the measured intensity images is then performed to obtain the RI distribution of the sample. As a proof-of-concept, we measured both microspheres and biological cells.
