Mathematical Analyzing of Laser Triangulation System without Scheimpflug Condition via C++ and Qt Framework

Abstract

In this paper, the mathematical characteristics of a laser triangulation system have been analyzed without considering Scheimpflug condition. The system parameters have been investigated and detailed information about the behavior of the system due to the changing some initial parameters just before designing the profile measurement system have been obtained. To be able to evaluate the system, C++ and Qt framework have been used for calculation of multi-dimensional arrays and visualization of the results to investigate the system parameters. The characteristics of the triangulation systems (both for our model and the model that proposed by Lamott and Noll, 2011) and characteristics of laser beam (laser beam thickness change for given measurement field range) for different laser sources with different wavelengths have been investigated. After analyzing the parameters of the triangulation system successfully, an adjustable system will be built in the laboratory to be able to get a better understanding the usage of this system in both 2D and 3D laser cutting systems.
