Abstract
The paper deals with the problem of obtaining weak signals in terms of background noise and the possibility of reducing the influence of outside lighting probed volume nephelometer. The author offers a variety of ways: the use of the design features of a nephelometer, the restriction of the field of view of the system, the installation of hoods, the installation in the construction of light absorbers, the use of modulation of illumination, circuit solutions in the receiving part (active and passive filters), hardware and software solutions for the subtraction of the background portion of the signal from the received signal based on the previous state of the optoelectronic tract.
