Abstract
A laser gas detection system includes a laser gas detector and a near-eye display device. The laser gas detection system provided in the present disclosure incorporates modern display technologies and modern communication facilities to present detection results to a user of the laser gas detection system in various intuitive and highly readable forms. The laser gas detection system is further capable of projecting the detection results to a field of view of the user through the near-eye display device.
Claims17
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.
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.
A non-transitory computer readable storage medium storing instructions for operating a laser gas detector, when the instructions are executed by a processor of the laser gas detector, the laser gas detector is configured to perform steps 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.
