Acousto-optic scanning system with fast non-linear scan

Nir Davidson (Inventor), Nir Friedman (Inventor), Ariel Kaplan (Inventor)

Research output: Patent


An acousto-optic scanning system, which relies on two counter propagating acoustic waves with the same frequency modulation. This scheme completely suppresses the linear frequency chirp, and thus enables the generation of fast non-linear scans and non-constant linear scans. By changing the phase between the modulating signals, this scheme also provides fast longitudinal scans of the focal point.
