Abstract : This Final Report summarizes the development status of a simple yet relatively smart electro-optical system that has been devised to do real-time monitoring of the optical state of the atmosphere. The system concept has been built around three solid state, no moving parts, transducer assemblies interfaced with a small dedicated microprocessor that can control the system in either a semi-automatic, or an operator interactive mode. The development status at the conclusion of this shortened contract interval is such that; a) each of the system sub-assemblies has been evaluated in a operational mock-up configuration, b) each has performed adequately to indcate technical feasibility, and c) the miniaturized nephelometer and on-board computer systems have been developed and fabricated to the prototype hardware stage.
