Non-contact laser methods for study of atmospheric, urban, industrial or pharmaceutical aerosols are widely used for determination of their parameters. The unique possibility of measurement of concentration, size distribution, flow velocity, absorption, refractive index, shape-factor and other characteristics of aerosol particles by remote sensing using lasers, gives a number of benefits in comparison with other measurement methods. After development of a dozen of different instruments for aerosol measurements using lasers - e.g. laser particle counters and sizers, aerosol spectrometers, laser Doppler velocimeters, aerosol analysers, we present an overview of modern techniques and their application in study of air contamination of the atmosphere, aerosol drug delivery in human airways, determination of filtration conditions in operating theatres and industrial firms, etc.
