Classification: CPC G  H | IPC G  H

Claim 6:
7. A method of operating a laser gas detector, the method comprising:
emitting a detection laser beam;
receiving an echo signal of the detection laser beam;
analysing the echo signal to determine a gas concentration parameter of a detection path along which the detection laser beam travels;
establishing a communication connection to a near-eye display device;
transmitting the gas concentration parameter to the near-eye display device for the near-eye display device to project the gas concentration parameter to a field of view of a wearer of the near-eye display device; and
transmitting directional information corresponding to the detection path, so that the near-eye display device combines and projects the gas concentration parameter and the directional information corresponding to the detection path to the field of view of the wearer of the near-eye display device.
