Abstract:
A light scattering apparatus and methods for using a light scattering apparatus that performs at angles other than the standard 90 or 180 degrees and can analyze a variety of samples including, but not limited to, solids, crystals, liquids, gases and combinations thereof.
Abstract:
A laser system simulates heat flux levels of rocket motor output. A laser is mechanically associated with a platform. The laser is configured to emit an electromagnetic beam. A plurality of positions are associated with the platform. Optical elements are associated with the platform. Each optical element is positionable in a plurality of positions without changing a location of the corresponding positioner. The optical elements are arrangeable into a plurality of combinations corresponding to at least one optical path beginning at the laser and terminating at a sample. Each combination corresponds to one of a plurality of distinct permutations of operatively positioned optical elements that reducingly interact with an emitted electromagnetic beam, yielding one of many versions of the emitted electromagnetic beam that is incidented upon the sample. Each version of the emitted electromagnetic beam that is incidented upon the sample has a lower power than the emitted electromagnetic beam.
Abstract:
An apparatus and method for use on precision refractive index experiments that are performed on individual faces of single crystals or liquid surfaces of material using specific wavelengths of light. The process is used to measure the major and minor axes of the optical indicatrix of a single crystal of material at a very specific wavelength. This process is repeated for each crystal face in order to form a complete picture of the refractive index for the sample.
