Labview integration of the sensor.

Prototype sensors for OH, NO and CO have been set up at Texas A&M University. The Texas sensor for NO has been successfully tested with practical engines.

The NO sensor here in Darmstadt has been successfully combined with a LabView interface, which automatically acquires the data, and performs the data analysis. Long term measurements of up to 6 hours have been successfully performed. Currently, our goals are

• improving the sensitivity of the sensor
• extending the mode-hop free tuning range of the ECDL diode laser
• new applications for this type of sensor
