Patent number: 10823671Abstract: One or more light sources emit light within first, second, and third wavelength ranges through exhaust gas. The first and second wavelength ranges are characterized by first and second different absorption wavelength ranges of a background gas. The third wavelength range is characterized by an absorption wavelength range of a gas-of-interest. At least some of the light within the first, second, and third wavelength ranges is absorbed by the exhaust gas thereby providing modified light characterized by the first, second, and third absorption wavelength ranges. One or more detectors receive the modified light. A processing subsystem determines a temperature of the exhaust gas based on the modified light characterized by the first and second absorption wavelength ranges and a concentration of the gas-of-interest based on the modified light characterized by the third absorption wavelength range and the temperature of the exhaust gas.Type: GrantFiled: December 22, 2015Date of Patent: November 3, 2020Assignee: General Electric CompanyInventors: Rachit Sharma, David Kelly Moyeda, Chayan Mitra, Arun Kumar Sridharan, Anish Bekal, Eric YuHang Fung
