Abstract
This paper deals with sensing using laser range finders and improving or altering their characteristics using mirrors. The idea that is presented here is to use one or multiple mirrors to change the direction of the laser ray, thereby resulting in some characteristics that are not available to a simple laser range finder, such as: scanning in multiple planes, which can be useful in e.g. 3D scanning; or multiple observations of the same area in one scan, which in turn gives an increase in the reliability and measurement resolution. The methods are explained and sample applications are presented, including the use in the laser range finder based touch screen.
