Paper Abstract

Typically, for a high energy laser experimental program numerous parameters such as power, irradiance, phase, etc. must be measured in order to adequately characterize the system performance. Correlation between effect and cause in a timely manner becomes very important in minimizing experimental effort. To this end, an on-line minicomputer controlled measuring system was developed. The interfaces to this system necessary to accommodate a wide variety of instruments (i. e. , calorimeters, IR cameras, spectrometers, etc. ) for a specific experiment are few, with most additions only requiring a software change. Some system features discussed include: time indexing of data f or search, retrieval and correlation; real time data acquisition and control of diagnostic instruments; graphical display capabilities such as isometric and contour beam intensity plots, beam jitter, etc. ; and software capabilities such as cross and auto-correlations, fast Fourier transforms, and signal averaging.
