Abstract

A scheme for fast three-dimensional laser scanning using acousto-optic deflectors is proposed and demonstrated. By employing counter-propagating acoustic waves that are both chirped and offset in their frequencies, it is possible to simultaneously scan both in the axial and lateral directions. This scheme also has the added benefit of inherently compensating for spatial dispersion when ultra-fast laser pulses are used in acousto-optic multi-photon microscopy.
