Embodiment Construction
[0040] See figure 1 The detection tools required by the present invention include: collimator, total station and digital circuit. The digital circuit provides accurate trigger signals and synchronization pulses for the high-speed camera and the system under test. The trigger signal mainly triggers the rotation of the swing mirror and the high-speed camera to start recording images. The synchronization pulse is used to provide the frequency of the high-speed camera to record the image, the trigger signal and the synchronization pulse The rising edge is aligned to ensure that the swing mirror starts to rotate and the camera starts to record at the same time, so as not to introduce additional angle errors;
[0041] The invention uses the point light source generated by the collimator to simulate the target, and places a plurality of collimators on the target motion curve within the tracking range of the pendulum mirror. The center of the pendulum mirror is set to O, and the rotation ...
