Abstract

When dimensional measurement of a body are performed by laser beam scanning, some sources of errors must be taken into account and evaluated. They relate to: laser noise, non-linearity and reproducibility of the scanner movement, optics aberrations, body edge detection, data processing. The paper presents the results of error investigation in contact-less dimensional measurement by laser beam scanning.
