Abstract
Different accuracy enhancement devices have been and are being developed in order to improve the manipulation accuracy of microsurgeons. The paper presents a one-degree-of-freedom proof of concept of a laser deflection system for acousto-optic compensation of hand tremor. A recording of physiological tremor acquired in vivo during vitreoretinal surgery in a rabbit model was used for the present experiment. When operating with a hand motion input tremor amplitude of 4 microns rms, the average overall canceling error is 0.8 microns rms. The results obtained demonstrate the general feasibility of the concept of tremor cancellation in laser surgery by using acousto-optic deflection.
