Generalized Image Acquisition and Analysis
A Mathematical Model and Calibration Procedure for Galvanometric Laser Scanning Systems
Laser galvanometric scanning systems are commonly used in various fields such as three dimensional scanning,
medical imaging, material processing, measurement devices and laser display systems. The systems of such kind
suffer from distortions. On top of that they do not have a center of projection, which makes it impossible to use
common projector calibration procedures. The paper presents a novel mathematical model to predict the image
distortions caused by galvanometric mirror scanning systems. In addition, we describe a calibration procedure
for recovering its intrinsic and extrinsic parameters.
