The JJF 1219-2009 standard is aimed at calibrating laser vibrometers and covers the basic definition, calibration methods and related terminology of laser vibrometers. Laser vibrometers use laser interference technology to implement non-contact measurement of surface motion of objects, including velocity, Acceleration and displacement. The components of laser vibrometers, such as laser interferometers, signal acquisition processing circuits, and waveform output units, are described in detail in the specification, and relevant calibrated reference standards are provided. The cited literature includes vibration Impact Measurement terminology, laser interferometry calibration method, etc., to ensure that the instrument is calibrated accurately and conforms to the new metrology standards.
