| 摘要 |
The invention relates to the area of investigation of substances by means of optical means, in particular to study of liquid and gaseous media, and can be used for determination of dimensions of dispersed particles and numbers of those in volumes of water solutions, suspensions, emulsions, aerosols and dust in air. Device for determination of particles includes a source of laser radiation, dividing glass, cuvette (hermetic and continuous flow ones), diaphragm, Fourier lens, a screen with opening, those are optically connected and connected to the block of registration and data processing (BRDP); and photo-diodes that through electric transformer are connected to the BRDP. Technical result of the invention is in increase of functional capabilities of the device due to measurement of disperse characteristics of the particles with high accuracy. |
