Embodiment
[0023] A kind of vial leak detection device 100 based on dual-wavelength-TDLAS technology of this embodiment is used to detect the sealing degree of vial 11, comprising: laser 1, laser controller 2, fiber coupler 3, first collimator 4. A first detector 5 , a second collimator 6 , a second detector 7 , an acquisition card 8 and a computer 9 .
[0024] Laser 1 for an output wavelength of ν 1 The first laser beam and wavelength ν 2 of the second laser beam.
[0025] The laser controller 2 is electrically connected with the laser 1 and is used to control the temperature of the laser 1 to keep the temperature value constant.
[0026] The fiber coupler 3 is connected to the laser 1 through the optical fiber 10, and is used to divide the first laser beam into the first laser beam I whose laser intensity ratio is a and the first laser beam II whose laser intensity ratio is b and divide the second laser beam into The laser beam is divided into a second laser beam I with a laser inte...
