Abstract

A number of particle fields having a 1-D velocity distribution are recorded holographically by double exposure. The reconstructed fringe patterns in the Fraunhofer plane are sampled on-line using a linear photodiode array, and the computed velocity distributions are compared with the input functions. For wider distributions a velocity-shifting technique using a translating photographic plate has been applied to two liquid spray systems.
