Abstract: A photobioreactor system includes vessel for containing a biomass and a plurality of illuminators which may have solid state devices embedded therein or coupled thereto. The light energy is distributed in the vessel volume by the illuminators so as to reach substantially all of the biomass being circulated in the vessel. Biomass may exit the top of the vessel and be refreshed with nutrients and liquid before being reintroduced at the bottom of the vessel. Carbon dioxide is introduced at the bottom of the vessel. The biomass may be agitated either ultrasonically or by motion of the illuminators. A source of energy for the light sources may be solar panels with battery storage and the carbon dioxide may be a byproduct of thermal power generation.

Abstract: An apparatus for performing Raman spectral analysis of a sample is described, comprising a coherent light source, an first optical chain to direct the coherent light to impinge on the sample, a second optical chain to direct the scattered light onto a diffraction grating, and a third optical chain to direct the diffracted light onto detection array. The diffraction grating is a plurality of alternating-slope stairsteps, wherein the portion of the step disposed parallel to the base of the diffraction grating is disposed so as to be orthogonal to the path of the scattered light from the second optical chain. The zeroth-order fringe is selected by a slit and directed onto camera. The resultant interferogram is Fourier transformed to produce a representation of the Raman spectrum.
