The design and application of laser triangulation ranging system based on virtual instruments

Laser triangulation ranging is a method of distance measure using laser as the light source and based on the triangulation ranging principle. It has many advantageous characteristics such as non-contacted measurement, high accuracy, and a large degree of strength against disruption. As a result, it is widely used in the industrial production. An integrated real-time laser triangulation ranging system based on virtual instruments is introduced in this paper. The measuring principle, the hardware components and the real-time virtual instrument program are introduced. As well as, the results of the measurement are presented and analyzed.
