description The invention discloses a vibration measurement method and system based on single-frequency laser feedback. When a single-frequency helium-neon laser device is in a strong feedback level, the laser device is influenced by multiple high-level feedback to produce high-density feedback optical stripes, and each feedback optical stripe has high measuring resolution to perform vibration measurement. According to the vibration measurement system, the laser device is used as a sensor for vibration measurement, and the vibration measurement system has the advantages of simple structure, high cost performance and the like; the enclosing laser device is not sensitive to temperature, and has good resistance to electromagnetic interference. Particularly, when the feedback level of the laser is high, the multiple high-level feedback effect is utilized, the high-density feedback stripes with polarization transition can be obtained; vibration amplitude on the sub-micron level can be measured, and the vibration measurement s
