One of the most rapidly developing areas in laser velocimetry is concerned with measuring aerosol velocity using methods that do not directly depend on the coherence properties of the laser. These methods do not rely on an interferometric measurement of the Doppler shift in the scattered light frequency to determine particle velocity. Some other method such as time of flight between two or more beams, particle arrival rate through a single beam, or pulse shape analysis is used. In this column I want to discuss some relatively recent work in the development of these techniques.
