Abstract A multifunctional laser aiming detector applied on coordinate measurement machines was designed based on half facular point optical imagery.The designing thought and operation principle of the multifunctional aiming detector optical system was described 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 measurement experiments, linear sensitivity aiming measurement experiments and inclination tracking measurement experiments of the multifunctional detector were conducted in practice.The experimental results show that the measurement uncertainty of laser tracking aiming repeatability of the multifunctional detector is less than 1 μm with the measurement sensitivity of 30 mV/μm after calibration.The angle measure scale of laser tracking aiming is expected to 25° without any other accessorial equipment, which can be met the requirements of CMMs.This detector with characteristic 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 measuring instruments and have a wide range of application prospects and a strong practical value for measuring parts profile with a higher precision.
