However, the transduction of light in silicon present losses due to recombination processes, and only a portion of the generated electron-hole pairs end up contributing to the detectable current Iopt, which always is lower than Iph, depending on the quantum efficiency η as indicated in (7): ...
time-domain NIRS;null source-detector separation;brain;diffuse optics 1. Introduction Among the fascinating applications of lasers, the non-invasive/non-destructive analysis of diffusive samples [1] (such as biological tissues, fruit, chemicals and wood [2,3,4]) has recently gained a lot of int...
