An optical system has been developed for a device for recording biological aerosols, based on a low-power pulsed-periodic UV laser. The possibility of differentiating aerosols of dust, protein, and bacterial spores by means of the given device has been experimentally checked. It has been investigated how the design parameters of the optical system thus developed affect the solution of the problem of classifying aerosols of various substances. Data are presented on the anisotropy of the fluorescence radiation of aerosol particles.
