Optical System Fault Management (OSFM )  Current Development Work for USAF  Provide software maintenance monitoring system for the Airborne Laser Optics and Diagnostics System.  Create intuitive interfaces for operators to access sensor data and evaluate past events  Supported by Small Business Innovative Research Grant (SBIR) – Kirtland AFB and MDA Note: A key goal in SBIR program is to create dual- use technology (military/commercial).

Various Markets for Diagnostic Software  Software modules developed for military and commercial laser manufacturers  Image analysis algorithms to assess beam quality  Intuitive User Interface  Archiving of performance data  Real-time remote control of actuators, etc in beam path. Provide remote diagnostics and assessment of field-based laser systems Industrial Lasers Medical Lasers

Why Develop this Software? A need exists to monitor high value optics in critical laser systems  Identify degradation on key subsystems using sensors  Monitor high value optics during operation  Assure consistent performance over time  Provide laser operators with easy access to laser data  Provide an intuitive interface to look at current and historic data.  Access historic data and compare with current data  Complex problems can have complex history

Remote Diagnostics & Data Sharing Performance Databases ABL Laser Operators Sensors Integrated into Laser EZ access to data Graphical Interface Data Logs

Real-time and Historic Data  View data from Laser during operation  View multiple feeds from data sensors  Archive data into database  Compare current data from historic data  Access historic data from database  Compare trends, max/min data points, etc. or

Current Software Development  Access Data from sensors on Laser  Exchange data with a commercial database.  Create a toolkit that allows the operator to easily manipulate sensor data and track trends.  Create a Drag ‘n Drop tool to assign sensors to specific optics.  User tests

Ex: Interface Screen to Laser Data Colored indicators for “quick view” of status Detailed values also available Trend data available for comparison of different inputs User selected windows for different data Example screen

Optical System Fault Monitor Software  Current status:  Gets average, min, max, and histogram of intensity values  Sets (and gets) polygon bounds between image and background  Converts between color schemes  Converts to binary, gets skeleton image, centroid, ratio  Inverts, softens, copies, crops, zooms in and out

Under Development  Peak position and centroid  OSFM already calculates these  User needs to specify threshold  Intensity distribution w/histogram  Total and peak power  Beam width measurements (integrated power).

Next Additions  User-specified aperture  Add circle, ellipse to polygon  3D graphics  Percent power within aperture  Uniformity: formula, convert integrals to sums  Limit calculations to user-defined areas

Statistical analysis  Mean, standard dev, min, max, graph of any calculation over time  Slope/regression line  Pass/fail notification with min/max parameters Note: Pass/Fail notification can be automated with alerts being sent to maintenance personnel

 Image processing block has been developed that incorporates image manipulation algorithms from Cybernet’s library:  Edge-finding  Feature extraction  Image comparison  Image format translation  Images can be displayed statically, as a sequence, or as full-motion video (FMV). Image Processing

Database on Central Server  Centralized storage of data from individual lasers in the field  Secure, accessible  Structure based on existing Web database developed for medical data.  Supports searches, archiving of data  Instant Access to Maintenance Documents Example of Database Screen from Cybernet’s Medical Server

Drag’n’Drop Laser Bench Configuration Editor  In order to be flexible, our system design includes a tool for defining the optical component train and sensors used to monitor it.  This is a visual aid to “link”a given sensor to a given location on the laser bench.
