What is it about?
Optical imaging technology for depth resolved visualization of the changes in sub-micron structure with nano-sensitivity is proposed and discussed. Results of numerical simulations and experimental imaging of phantoms and medico-biological objects, including human skin in vivo, confirm possibilities of the technique.

Why is it important?
Most of the fundamental pathological processes in living tissues exhibit changes at the nanoscale. Presented technique permits noninvasive, label-free depth resolved detection of structural changes in biological samples with significant Improvement in sensitivity, up to nano-scale.
