BINNING AND TOMOGRAPHY FOR HIGH SPATIAL RESOLUTION TEMPERATURE AND SPECIES CONCENTRATION MEASUREMENTS

摘要

A method of absorption spectroscopy including obtaining absorption data a t multiple wavelengths along more than one line-of-sight path through a quan tity of gas of interest. The method further includes identifying more than o ne temperature and gas species concentration bin along the multiple line-of- sight paths and creating a map of temperature and gas species concentration. The map thus created will have at least two-dimensional information derived from select temperature and gas species concentration bins identified along more than one line-of-sight path. Apparatus for implementing the above meth od is also disclosed.
