Professor Zhu attended the seminar on laser interferometers

The DFI-6 laser interferometer has the advantages of high measurement accuracy, large measurement range, fast measurement speed, and high resolution at the highest speed measurement. Combined with different optical mirror groups, it can achieve high-precision measurement of geometric parameters such as linear length, angle, straightness, perpendicularity, parallelism, and flatness. With the help of DFI-6 laser interferometer dynamic measurement software, dynamic measurement and performance testing of linear displacement, angle and straightness can be achieved, as well as dynamic analysis of displacement, velocity, acceleration, amplitude and frequency, such as vibration analysis, dynamic characteristic analysis of screw guide rail, response characteristic analysis of drive system, etc.
