Abstract

A diffraction phase microscopy approach with a combined use of transmission and reflection imaging modes has been developed and applied for non-invasive quantitative assessment of the refractive index of red blood cells (RBCs). We present the theoretical background of signal formation for both imaging modes, accompanied by the results of experimental studies. We demonstrate that simultaneous use of the two modes has great potential for accurate assessment of the refractive index of biological cells, and we perform a reconstruction of spatial distribution of the refractive index of RBC in 3D.
