===== LPRS instruments and techniques =====

//Laboratory techniques//:  

  * Bi-directional reflectance measurement device, with both incident and viewing zeniths vary from 0 to 65 deg., spanning a phase angle range of 2.7-130 deg., at 3 wavelengths: 0.633, 0.532, and 0.473 micron (currently only data at 0.633 micron available); measurements are done in the principal plane only.
  * FT-IR reflectance spectra of minerals
