Abstract

The AGLITE-LIDAR instrument is a three-wavelength lidar system being designed and constructed at the Space Dynamics Laboratory under contract from the Agricultural Research Service. Its purpose is to implement a novel new approach to making measurements of gas and particulate pollutants released into the atmosphere by agricultural operations. Once operational, it will provide a means whereby the total flux of pollutants being emitted by agricultural facilities might be measured. This approach is valid even for facilities that may cover several acres. The design of the AGLITE instrument consists of a myriad of different components that are brought together in a strictly coordinated system. The overall design is broken into three main categories: the mechanical, optical, and electrical designs. The electrical design is equally essential in the operation of the final instrument as the mechanical and optical aspects and is closely intertwined with their workings. The electronics include all of the sensors and detectors, the data acquisition systems, the component control and synchronization circuitry, and the computers and data links. Combined with software, these allow the overall control of the system. This report documents the complete design of the electronics system for the AGLITE instrument from the conceptual layout of the instrument to the final fabrication. It is divided into two main portions. First, the high-level system design covers the scoping of the electronics system and the layout of the system architecture. It explains the major design decisions that were made before arriving at the implementation plan. The second portion of the report covers the detailed design of the electronics proceeding even to the circuit level where appropriate. It fully documents the critical details of the final system.
