Claims
- 1. A method for determining and displaying the spacial distribution of a selected spectral pattern received light comprising the steps of:
- collimating said received light;
- passing said collimated light through an interferometer having a moving mirror;
- focusing the light that has passed through said interferometer as an image onto a focal plane array of pixels of a digital framing camera;
- repetitively sampling an intensity of said image in said digital framing camera to provide digital frames of the intensity of said image as a function of the position of the moving mirror;
- storing said digital frames of the intensity of said image in a memory;
- coupling the stored digital frames of the intensity of said image to a computer;
- calculating in said computer a Fourier transform of each of said stored digital frames of the intensity of said image to provide spectra for every pixel in said array;
- filtering said spectra for the selected spectral pattern in said spectra for every pixel in said array to provide an image of said spectral pattern across said array; and
- displaying said image of said spectral pattern on a video monitor to provide the spacial distribution of said spectral pattern.
