Beschreibung
Zusammenfassung:	The invention discloses a self-adaptive laser shock peening device and method. A laser, an energy attenuator, a spatial light modulator and a Z-axis displacement platform are sequentially arranged on the same laser light path on an X-axis displacement platform and a Y-axis displacement platform; the focusing system is mounted on the Z-axis displacement platform, and the absorption layer is bonded on a processed sample and fixed on the X-Y-axis displacement platform; a material distortion detection device and a CCD camera are arranged on one side of the focusing system, and a temperature sensor is arranged on the other side of the focusing system; the water flow pipe emits constraint layer water flow to the processing sample; the computer analyzes information detected by the material distortion detection device, the CCD camera and the temperature sensor, and controls the Z-axis displacement platform, the energy attenuator and the spatial light modulator. By introducing the material distortion detection system,
