Abstract
The invention discloses a gas leakage scanning imaging device and method, belongs to the technical field of gas detection, and aims at solving the technical problems that in the existing gas detection technology, the imaging process is tedious due to the fact that a device needs to be calibrated, and the imaging accuracy is low due to equipment shaking in the scanning process. The device comprises a visible light imaging module, a TDLAS scanning module, a signal synchronous acquisition module and a data processing unit. The TDLAS scanning module comprises a detection light emitter, an indication light emitter, a dichroscope, a light beam angle control module, a receiving unit and a control processing unit; the detection light emitted by the detection light emitter and the reference light emitted by the indication light emitter are incident to the dichroscope for beam combination, the combined light beam is irradiated to a background object after passing through the light beam angle control module, and the combined light beam generates diffuse reflection on the surface of the background object and is received by the receiving unit; and the beam angle control module controls the angle to enable the combined beam to scan a background object at different angles.
