摘要：
Methods and systems enabling the real-time monitoring of a light-inducedprocedure in abiological medium, and/or the acquisition of information related to thisbiological mediumare provided. In some implementations, the light beam used for the procedureismodulated at a modulation frequency selected in view of the photoacousticfrequencyresponse associated with the procedure. The photoacoustic feedback signal fromthemedium during the procedure is then monitored. This monitoring may involvefiltering thephotoacoustic feedback signal around the selected feedback modulationfrequency.Ratiometric comparisons of the contribution of different frequencies to thephotoacousticfeedback signal are also considered.
