| Abstract: | A deconvolution fitting algorithm is applied to recover the real optical pulse signal in time resolved system, from which the optical parameters of the media can also be withdrawn. In model experiment simulating optical properties of human tissue, time-correlated single photon counting system is constructed to measure the photon escaped curve. Then the fitting algorithm is verified when calculating the optical parameters of the media. |
