The optical properties of biological tissues and, more specifically, to enhancing the light delivery efficiency into tissues, so that the light penetration depth can be improved for optical techniques currently applied to biomedicine. The optical techniques concerned may include optical imagining techniques, therapeutic techniques (including photodynamic therapy), laser surgery, and other optical diagnostic techniques that are based on light scattering, absorption, polarisation and the flourescence properties of tissues. In addition, the invention may also apply to the optical imaging based diagnostic techniques where the goal is to enhance the local imaging contrast within tissue. |
