1. A laser gas detector, comprising:
an emitter configured to emit a detection laser beam;
a receiver configured to receive an echo signal of the detection laser beam and analyse the echo signal to determine a gas concentration parameter of a detection path along which the detection laser beam travels; and
a communication interface configured to:
establish a communication connection to a near-eye display device;
transmit 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
transmit 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.
