Abstract: An optical system employs filtered broad band light for determining the specific components in a material sample. The system forms an r by n matrix C representing r principal components of the measurement to be analyzed at n different frequencies. Each sample contains a known quantity of the different materials in the sample being analyzed where r represents the number of different analytes or components in the sample. The system measures m different samples at n different frequencies, said m samples containing unknown quantities of the material, where “m” is a selected integer representing the number of samples. Using the measured results from the m samples the system forms an n by m matrix P, where P=C·R, and where R is an m by r matrix representing r unknown values of the r principal components which are being measured in the m material samples. The system then solves the equation P=C·R for R by inverting C in the equation R=(CT·C)−1·CT·P. This gives the value of each of the r principal components in the sample.
