Method and apparatus for improving the angular aperture of an aodlf

A method and apparatus for increasing the angular aperture of an acousto-optic dispersive light filter in which acoustic frequencies of differing frequencies are launched into a crystal at differing angles to each other. Input light phase matches with corresponding ones of the acoustic frequencies s...

Zusammenfassung:	A method and apparatus for increasing the angular aperture of an acousto-optic dispersive light filter in which acoustic frequencies of differing frequencies are launched into a crystal at differing angles to each other. Input light phase matches with corresponding ones of the acoustic frequencies so that the angular aperture is enlarged.
