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

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

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.
