    • Highly diffuse reflector 
      Fry, Edward S.; Musser, Joseph A.; Katz, Jeffrey; Merka, William C.; Kattawar, George W.; Lu, Zheng (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2011-01-11)
      The invention relates an apparatus and method for forming a diffuse reflector. In one embodiment of the invention, a diffuse reflector is formed by exposing transmissive particles of a pre-determined purity to pressure and ...
    • Optical absorption of pure water in the blue and ultraviolet 
      Lu, Zheng (Texas A&M University, 2007-09-17)
      The key feature of the Integrating Cavity Absorption Meter (ICAM) is that it produces an isotropic illumination of the liquid sample and thereby dramatically minimizes scattering effects. The ICAM can produce ...
