The method of autodyne detection of backscattered radiation is used to study the passage of CO{sub 2} laser radiation through interfaces of model media and biological tissues in vitro during their laser perforation. It is shown that a stepwise change in the weighted mean frequency of the autodyne-signal power spectrum is a criterion for this passage in real time.
