A Design of Multifunctional Laser Aiming Probe

Abstract:

A multifunctional laser aiming probe applied on coordinate measurement machines was designed and presented in this paper based on half facular point optical imagery. The designing thought and operation principle of the multifunctional aiming probe’s optical system was introduced and analyzed in detail. An adaptive intensity control method was used in the circuit to adjust the laser intensity timely so that it can adapt to aiming measurement of different optical properties surface. Repeated aiming trigger experiment was conducted and the experimental results showed that the measurement repetitive standard deviation of the multifunctional probe was better than 0.5μm without any other accessorial equipment, which can be satisfied with the use requirements of CMMs. This probe with the characteristics of high detecting speed, high degree of automation and high aiming accuracy, will be expected to have the ability of free curved surface and imagery tracking aiming measurement of contour with higher speed and accuracy coincided with CMMs or other length measurement instruments and have a wide range of application prospects and a strong practical value in measuring for parts profile with a higher precision.
