Abstract: Non-differaction beam is a new research field which has been given more and more attention recently both at home and abroad.It has properties of long focus depth and small central spot.For these properties,the authors apply it as incident beam to resolve the main problem in traditional laser triangulation measurement,which is high resolution and large measurement rang can not be satisfied meantime.Theory and generation method of non-diffraction beam have been given.Basing on the relationship of object-image position,structure parameters of the laser triangulation measurement system with non-diffraction beam has been designed and the experimental results have been given.The theoretical analysis and experimental results show that the novel system is better than the traditional triangulation systems clearly.
