Abstract A laser imaging system and method for detecting leakage is composed of laser device, cylinder filled with the medium to be detected, imaging instrument and monitor. Its detecting method features that the medium to be detected is first filled into the object, and the laser device is then turned on. When there is leakage, a temp different between the leakage gas and ambient axists. Under the radiation of laser, the image of leakage gas flow can be observed on the monitor.
