Acoustooptic spectrometer system used to monitor combustion processes.
An optical system using a tunable acoustooptic filter to measure the temperature and partial pressures of CO and CO(2) in combustion gases has been designed and operated. The system measures the IR absorption over a linear path through the combustion products from several lines of the vibration-rotation band of CO at 4.7microm. The temperature and partial pressure of CO are then calculated using these data. The IR absorption due to the asymmetric stretch of CO(2) is then measured. The entire system, under computer control, is self-calibrating and is well suited for remote process control use.
