Software Techniques for the Acquisition of Optical Data from a Minicomputer-Based Image-Intensifier-Vidicon System

摘要

The software required to support a new technique for acquiring large amounts of optical data in a short time period has been developed. The data acquisition system incorporates an image intensifier and vidicon tube in combination. It is controlled by a minicomputer utilizing the software described. The software handles all control of the image-intensifier-vidicon system, acquires the data from the system, and stores the data for subsequent retrieval and reduction. The software incorporates a disk operating system for a single floppy disk drive. This disk operating system utilizes a specially designed technique that optimizes the rate of writing data onto the disk. The system was implemented to acquire temperature and density data from the flow of a rocket engine exhaust plume. This application coupled the system with an electron beam mechansim to acquire the data using and electron beam fluorescence technique. This application was used to verify that the system meets the requirements set forth for it. (Author)
