Abstract

A mid-IR (MWIR) optical emission spectrometer (OES) was designed and constructed to detect the absolute spectral radiant exitance of IR signatures. A 256-array PbSe detector was adopted to analyze the MWIR emission spectrum. Various IR signatures from two flame sources were examined in order to evaluate the performance of the OES and verify its usefulness for low observable technology. The absolute emissions of their IR signatures were calculated and the amount of each emission was compared. The spectral response of the OES in the MWIR range was calibrated using a directly heated graphite blackbody; in addition, the total uncertainty of the OES was determined to be 5.24%.
