Effect of optical magnification on the detection of the reduced scattering coefficient in the blue regime: Theory and experiments

Imaging turbid media is range limited. In contrast, sensing the medium's optical properties is possible in larger depths using the iterative multi-plane optical properties extraction technique. It analyzes the reconstructed reemitted light phase image. The root mean square of the phase image yields two graphs with opposite behaviors that intersect at µ'_scp. These graphs enable the extraction of a certain range of the reduced scattering coefficient, µ'_s. Here, we aim to extend the range of µ'_s detection by optical magnification. We use a modified diffusion theory and show how µ'_s,cp shifts with the varying magnification. The theoretical results were tested experimentally, showing that the technique can be adapted to different ranges of µ'_s by changing the magnification.
