Piezoelectric Active Tremor Compensation System for LASER Microsurgery - Constructive Solution

Abstract

Two alternative constructive solutions for active vibration compensation systems with applications in LASER microsurgery were conceived and simulated. The aim is to select one of them and construct it in order to test the actual capabilities against the estimated performance. Both solutions are based on piezoelectric actuators of different types which require different approaches in controlling the path of the LASER beam. Aspects regarding the geometry of the solution, command and control requirements, mechanical complexity and reliability, potential for ergonomic improvements, were taken into consideration. Capabilities to compensate tremor amplitudes up to ± 5.1 mm were estimated.
