Abstract
A method and apparatus for characterizing and screening an array of material samples is disclosed. The apparatus includes a sample block having a plurality of regions for containing the material samples, a polarized light source to illuminate the materials, an analyzer having a polarization direction different than the polarization direction of the polarized light source, and a detector for analyzing changes in the intensity of the light beams. The light source, together with a polarizer, may include a plurality of light beams to simultaneously illuminate the entire array of materials with linearly polarized light so that characterization and screening can be performed in parallel. In addition, the materials in the sample block maybe subjected to different environmental conditions or mechanical stresses, and the detector analyzes the array as a function of the different environmental conditions or mechanical stresses.
