Abstract

The conventional color video image was regarded as a compound image representing energy distributions of three wavelengths such as R.G.and B. These wavelengths were convenient to reconstruct the natural color images. However each of these representative wavelengths could not have clear information concerning self-luminescence events like combustion phenomena. A high-speed video optical system, so called “Multi-Spectral Optics” which had four optical paths for objective wavelengths was developed. The principle of the optics was a new simple multi-spectral beam splitting optics to obtain four images of different wavelengths. By setting the wavelengths as to correspond to representative wavelengths of self-luminescence event, many kinds of information could be derived by image-analysis of among four images captured by this system. The optical system developed here and its feasibility study in combustion analysis are reported in this paper.
