Abstract
An optical velocimetrical probe comprises means to illuminate a volume of measurement in which particles may pass, and optical detection means to produce an electrical signal x(t) in response to the passage of a particle in the illuminated volume. It also comprises means to extract information representing the velocity v of particles from the electrical signal, these means comprising,in particular, means to compute the density of probability p(x,.theta.) of the signal vector x(t), means to determine a frequency representing the velocity v for which this probability is the maximum.
