Abstract :
An amorphous silicon photodiode array originally manufactured for facsimile has been applied to a velocity meter based on the spatial filtering method. An adoptive modification of the reticle pitch of the filter can be achieved by grouping the photodiode elements for wide range velocity measurements. Particle velocity measurements are also presented
