Abstract: An open path gas detection system (200, 280) includes a transmitter (202, 202A) and a receiver (204). The transmitter (202, 202A) is configured to generate illumination (106) across an open path. The receiver (204) is positioned to detect the illumination (106) from the transmitter (202, 202A) after the illumination (106) has passed through the open path and detect a gas of interest based on the illumination (106). However, the laser can also be used for gas detection systems in other circumstances. The transmitter (202, 202A) and receiver (204) are configured to communicate wirelessly (120). A method (500) of operating an open path gas detection system (200, 280) is also provided.

Abstract: An open path gas detection system (200) includes a transmitter (202) and a receiver (204). The transmitter (202) is configured to generate illumination (216), having broadband spectrum, across an open path. The receiver (204) is positioned to detect the illumination (216) from the transmitter (202) after the illumination (216) has passed through the open path. The receiver (204) includes at least one spectrometer (218) configured to determine spectroscopic information of the illumination (216) to identify at least one gas of interest based on the spectroscopic information and provide an output (222) based on the at least one gas of interest.
