Item Method for high speed microscopy with three-dimensional laser beam scanning(2008-02-19) Saggau, Peter; Reddy, Duemani; Iyer, Vijay; Baylor College of Medicine; Rice University; United States Patent and Trademark OfficeA system and method for independently controlling the collimation and lateral positioning of a light beam comprises at least one acousto-optic deflector and a pair of counter propagating acoustic waves with offset frequencies. While the frequency offset controls the lateral positioning of the light beam, a frequency gradient across the acousto-optic deflectors controls the collimation of the light beam.
