Abstract
In this paper we propose a functional diagram of an apparatus for measuring the dependence of half-width of the scattering spectrum on the wave vector modulus in real time. The use of a fiber-optic sensor and a running wave interferometer should allow measurements directly within chemical reactors. Results of calculation of the output signal amplitude in dependence on interferometer parameters are presented.

KEY WORDS: nanoparticles, dynamic light scattering, correlation spectroscopy, optical fiber sensor, running wave interferometer, chemical reactor
