Optical excitation based imaging modalities, with aim to image structures deep inside the scattering medium, suffer from quantification problem. We propose a methodology to solve the problem of non-invasively mapping the fluence in optically heterogeneous medium without the need of prior knowledge of its optical properties. We present a theoretical model of our concept and provide proof of principle with Monte Carlo simulations. Simulation results show that it is possible to measure the local light fluence in highly scattering medium in absolute terms. Furthermore, we performed an experiment to validate the concept as a strategy to measure local fluence in relative manners. We used reflection mode acousto optics (AO) in our experiment, and showed that with this method we can measure local light fluence (in relative term) in highly scattering medium. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
