| Abstract: | Aiming at the impact of digital speckle pattern interferometry on vibration measurements,the calibration of digital speckle pattern interferometer is discussed.Based on the piezoelectric vibrating table with sine excitation and the laser vibrometer with high precision,a calibration system is built.The accuracy and reliability of the calibration system is investigated by repeatability experiments.Finally,a self-developed digital speckle pattern interferometer was calibrated with the calibration system.The re... |
