Abstract

A simple optical multichannel analyzer consisting of SIT vidicon camera, videotape recorder, and video digitizer was used to record coherent anti-Stokes Raman scattering N2 spectra for temperature measurements inside a firing internal combustion engine. A high-resolution spectrum was recorded from each engine cycle at a 10-Hz repetition rate. Thousands of spectra were rapidly stored in inexpensive nonvolatile memory (videotape) to be digitized and analyzed later for the generation of temperature histograms. In addition to this spectroscopic application, the same equipment can be used for fluid dynamic and combustion imaging experiments.
