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

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

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
www.cybernet.comwww.cybernet.com
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).
www.cybernet.comwww.cybernet.com
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
www.cybernet.comwww.cybernet.com
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).

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.
