MULTI-HARMONIC INLINE REFERENCE CELL FOR OPTICAL TRACE GAS SENSING |
摘要 |
A spectroscopic sensor and a spectroscopic method of determining a concentration of a sample are disclosed. The sensor is used in connection with a sample cell containing a sample. The sensor includes a coherent light source configured to transmit an interrogation light beam along an optical sample path directed towards the sample. The sensor also includes an in-line reference cell located in the sample path. The sensor also includes a detector having outputs responsive to absorption signals from the sample and the in-line reference cell. The sensor also includes a processor configured to isolate the reference absorption signals from the in-line reference cell and sample absorption signals from the sample cell and generate calibration information based on the reference absorption signals and determine a concentration of the sample based on the sample absorption signals. |
