Fast Three-Dimensional Laser Scanning using Acousto-Optic Deflectors

摘要

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