    • Characterizing powders using frequency-domain photon migration 
      Sevick-muraca, Eva M.; Sun, Zhigang; Pan, Tianshu (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2004-08-03)
      Characterizing a powder bed includes generating measurements by repeating the following. A location of the powder bed is illuminated with light having a time varying intensity with a resolution of less than one hundred ...
    • Method for characterising particles in suspension from frequency domain photon migration measurements 
      Sevick-Muraca, Eva M.; Sun, Zhigang; Huang, Yingqing (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2007-09-11)
      Methods are provided for measuring isotropic scattering coefficients of suspensions using multiply scattered radiation that is modulated in amplitude at selected modulation frequencies. The radiation may be light. Quantities ...
