Figure 2

Plot of the experimental and Monte Carlo simulated temporal point spread function (TPSF) measured at two different depths in the liquid phantom. (a) The tips of optical fibers at the depth of 0.5 mm. Solid brown line, experimental TPSF (measurement); Dotted line, simulated TPSF (MC). (b) The tips of the optical fibers at the depth of 1.1 mm. The MC simulated TPSF was convoluted by the instrument response function (IRF).
