Scanning rack flatness calibration device and calibration method thereof

Abstract

The invention discloses a scanning rack flatness calibration device and relates to the technical field of laser measurement. The device includes a laser emitter and a Z-axis collecting rack; a magnetic surface base is movably connected to one side of the Z-axis collecting rack, a laser receiver is movably connected to the side, away from the Z-axis collecting rack, of the magnetic surface base, and the laser emitter emits rotary laser beams. According to the method, the laser receiver is placed on the Z-axis collecting rack through the magnetic surface base at first. By means of the scanning rack flatness calibration device and the calibration method thereof, the problem that only double theodolites or laser tracing instruments can be adopted for existing measurement of the spatial flatness can be well solved, the prices of the expensive instruments are greatly reduced, and the requirements for the professional level of testers are relatively low, so that the device is extremely suitable for application in small-scale companies. Meanwhile, the adjustment cycle is well shortened, the purpose of improving the flatness of a scanning rack is achieved, and therefore more convenience isprovided for people to calibrate scanning racks.

Description

technical field [0001] The invention relates to the technical field of laser measurement, in particular to a scanning frame flatness calibration device and a calibration method thereof. Background technique [0002] The scanning frame is used to cooperate with the test of the amplitude and phase consistency of each channel of the array antenna. It is a key component in the entire near-field measurement system. For antennas of different frequencies, different precision scanning frames are required. This patent introduces the rotating laser measurement The application of the plane in the flatness calibration process of the scanning frame, using the StatusPro rotating laser measurement system to measure and calibrate the flatness of the scanning frame, has been applied to several scanning frame projects, and the calibration results are compared with the measurement results of the laser tracker , the two measurements are consistent. [0003] At present, the measurement of spati...
