Abstract: A method of assessing optical properties of surgical tissue by observing the tissue thermal response to laser irradiation includes exposing the tissue in a surgical region to a short laser pulse for triggering a localized temperature increase, and observing the triggered temperature increase by a thermal sensor. Optical properties of the tissue are then estimated, for determining laser surgery parameters for an eminent procedure, based on the observed temperature increase. In an example configuration, the thermal sensor is a thermal infrared camera, and estimation includes using an Ensemble Kalman Filter (EnKF) for comparing the temperature sensor data with the output of a computational laser-tissue interaction model.
