Paper Abstract

The identification of gases and the measurement of their concentration in a mixture is important in a variety of applications such as gas leak detection, process monitoring and control, and pollution control. Many gases can be uniquely identified by their optical absorption spectra. In a mix of gases, the individual species can be identified by measurements at several wavelengths and the knowledge of the absorption strengths. The advantages of these optical absorption techniques can often be utilized to the fullest only if the technology used is capable of measurements over a wide wavelength range. Instruments based on pyroelectric array detectors can utilize both dispersive and nondispersive techniques, and operate over the entire infrared region since the detectors themselves are not intrinsically wavelength sensitive. In this paper, the construction and use of infrared pyroelectric arrays suitable for gas detection and monitoring are described.
