Abstract

The presented paper demonstrates the ongoing results of the joint research of University of Latvia and Riga Technical University aimed at the development of new laser based optical methods and technologies for fast evaluation of microbial activity in solid media. The second part of the paper represents the results of joint research conducted together with Katya Borisova during our visit to the Institute of Electronics, Bulgarian Academy of Sciences (Bulgaria, Sofia).
