An imaging technique called spectrally encoded enhanced representations (SEER) provides greater clarity and works up to 67 times faster and at 2.7 times greater definition than existing spectral imaging techniques, according to its developers at the University of Southern California (USC). SEER uses mathematical computations to parse data quickly and achieve simultaneous color visualization of the multiple spectral components of hyperspectral fluorescence images.
SEER transforms wavelength space into color maps for RGB display visualization using the phasor method. Originally developed for fluorescence lifetime analysis, the phasor approach is used by SEER to enhance the visualization of multi- and hyperspectral images.
