Monte-Carlo results. (a) Normalized sensitivity in a logarithmic scale as a function of depth for a point inclusion fluorescing at 710 nm, spread excitation beams at 633 nm and 670 nm and a point-wise detection. This mimics the spread excitation of a fluorescent source in an epi-fluorescence imaging system and the detection with a camera system. (b) Quotient of the normalized sensitivities shown in (a).
