20120170043 | Sensitive and Compact Sensor Employing a Visible Diode Laser and A High Finesse Optical Cavity for Trace Gas Detection (NO2) - A sensor with high sensitivity and selectivity for the detection of NO | 07-05-2012 |
20120113426 | Method and Apparatus for Trace Gas Detection Using Integrated Wavelength Modulated Spectra Across Multiple Lines - An apparatus and technique are invented that enhance the sensitivity of a spectrometer for trace gas detection by employing wavelength modulation spectroscopy (WMS) and integrating the absolute value of the recorded spectra across multiple absorption lines (features) of the species. The sensitivity is further enhanced by conducting WMS with large modulation depths. This technique is implemented using a continuously tunable external cavity CW quantum cascade laser to record the second harmonic wavelength modulated spectra of NO | 05-10-2012 |
20120062895 | Method and Apparatus for the Detection of Trace Gas Species Using Multiple Line Integrated Absorption Spectroscopy - An apparatus and method are used to enhance the sensitivity of a spectrometer (sensor) for trace gas species detection by employing an external cavity continuously tunable CW quantum cascade laser and integrating the absorption spectra across multiple lines of the species. With this method the absorption spectra of NO | 03-15-2012 |
