Abstract:

This patent discloses a method and apparatus for detecting the wavelength of singlet state resonance fluorescence of a sample, wherein the sample is illuminated sequentially with various incident wavelengths. For each wavelength, linearly polarized and circularly polarized components are allowed to pass sequentially by a first polarizer to the sample. The sample emits light as a result of spontaneous molecular energy transitions. Four components of the emitted light are allowed to sequentially pass to a detector by a second polarizer. The intensities of these components are then detected, and these values can be employed to obtain a new ratio for each wavelength at which this ratio equals one is selected as the wavelength of resonance fluorescence. In one example, a computer is provided to control the illumination of the sample and the two polarizers, and also may be utilized to computer the above ratios.
