Infrared temperature measurements in combustion systems
Abstract
A technique for gas temperature measurement which uses the infrared radiation from and absorption of a hog molecular species is described. The system was developed for measuring fluctuating temperature in combustion systems and transient temperatures in shock or detonation tubes. The detector signal is fed to an analog computation system which calculates the temperature in real time using Planck's and Kirchoff's laws. The output from the analog computer is a voltage proportional to temperature which can be recorded onto magnetic tape.
