Inverse problems of spectroturbidimetry of biological disperse systems: an overview.

The obtainment of stable solutions of inverse problems for studying the disperse composition of suspensions using effects of elastic light scattering was discussed. Versions of a regularization of solving the inverse problems of the spectroturbidimetric method were considered, taking into account unavoidable restrictions on the scope of the necessary prior data for particles and on the width of the spectral interval for real biological disperse systems. Possibilities for increasing the number of particle parameters determined in a single optical experiment were analyzed. They were shown to be provided by the use of effects of the orientation ordering of a system on combination of capabilities of the methods of spectroturbidimetry and electro-optics, using bacterial cell suspensions as an example. © 1999 Society of Photo-Optical Instrumentation Engineers.
