Abstract
The present invention is a method and apparatus for sequentially and repetitively diffracting multiple beams at a common predetermined angle. A coincident beam source introduces a plurality of coincident beams into an acousto-optic cell at a common location and angle, wherein each beam has a different wavelength. A signal controlling apparatus sequentially and repetitively introduces a series of signals to the acousto-optic cell. Each signal has a frequency, which corresponds to one of the multiple beams such that when the acousto-optic cell receives the signal, the acousto-optic cell operates at such frequency and diffracts the corresponding beam at the predetermined angle.
