Contemporary problems in experiments, theory and application of interest in ecology with lasers in laboratory and remote detection

Abstract

Multiple sensor systems and applications in ecology deserve multidisciplinary approach. Concerning laser implementation in monitoring, main parameters and processes have to be chosen in description of object of interest. The purpose of this paper is to underline the links and usability of scattering matrices in the description of biological objects (cells, nuclei, bacteria, etc). Light scattering processes are unavoidable in application and measurements, based on laser systems. Depending on the measurement systems, angular scattering and differential cross sections carry valuable information, and measurements should confirm chosen simplifications from theory. Shape recognition, size and chemical content could be certainly of interest in one part of ecological monitoring (water). Thermal imaging of objects depends on emissivity (water, ground, etc.) and some simplifications of derived cases are added to the previous.
