Abstract

An accurate optical sensing system has been developed to measure the position and orientation of a laser beam in two dimensions. The system is useful for evaluation of the accuracy of hand-held laser microsurgical instruments. The apparatus uses a lens and a beam-splitter to receive the incoming laser beam. Two position sensitive detectors placed at different distances from the beam splitter make it possible to rapidly and accurately calculate the position and orientation of the axis of the laser.
