Abstract
In this work, the local chemiluminescent intensities of OH* and CH* of a premixed laminar Propane/air bunsen burner flame have been measured. A multi-color integrated Cassegrain receiving optics (MICRO) is developed. The design of the optical system is optimized to minimize optical aberrations, especially spherical aberration. The effective light collection volume of the system is estimated to be a cylinder with 58 micrometers in diameter and 3.4 millimeters in depth. The Temporal resolution of the data acquisition system in this work is 2 microseconds. The effect of the equivalence ratio on the OH*/CH* signal is investigated and the calibration curve is extracted between the equivalence ratio and the OH*/CH* signal in a certain range of equivalence ratios for Propane/air combustion.
