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.

Abstract
After decades of research on digital representations of
material and object appearance, computer graphics has more
recently turned to the problem of creating physical
artifacts with controllable appearance characteristics.
While this work has mostly progressed in two parallel
streams – display technologies as well as novel fabrication
processes – we believe there is a large overlap and the
potential for synergies between these two approaches. In
this report, we summarize research efforts from the worlds
of fabrication display, and categorize the different
approaches into a common taxonomy. We believe that this
report can serve as a basis for systematic exploration of
the design space in future research.
