Description
Sudakou and colleagues worked out in 2026 new maths for diffuse optics, a method that reads tissue by watching how light spreads through it. Time-based versions record how long light takes to cross tissue. Analysts then turn shifts in that timing into shifts in how much light the tissue soaks up or scatters. Standard formulas assume tiny shifts, so large ones break their accuracy.
Sudakou extended the maths from tiny shifts to large ones, in uptake, scattering, and the gap between light source and sensor. Their formulas cover both deep tissue and surface tissue models, with no added guesses. They include a fixed form of a known light law used in steady-light tools. They also tested how wrong starting values skew the results, and how scattering shifts can fake uptake shifts. The work aims to sharpen light-based tissue readings in medicine.
