Design of a Miniaturization Laser Triangulation Probe
2015
This paper puts forward a new design idea of single lens according to the principle of optical triangulation. The minitype laser triangle probe is designed on the basis of the common direct laser triangulation whose light path is improved. A beam splitter lens is introduced to the path,and the focusing lens and imaging lens are into one. The beam splitter lens, detector and focusing lens are coaxial, so the system is more compact, and the whole measurement system’s volume is reduced. Optical system is simulated by optical design software ZEMAX( focus=20mm,Pupil diameter=4mm,and TOTR=20.5mm) , so the whole system can achieve miniaturization. With appropriate laser and photoelectric detectors , larger scope of work and higher precision of measurement is obtain. The system adaptability to the measurement environment is improved,and this system can be widely used in the industrial online detection and military fields.
