INNOVATION
The Disturbance-Optics-Controls-Structures (DOCS) Toolbox is a
software environment initially developed for end-to-end analysis of the dynamic performance of
controlled opto-mechanical systems. It provides an integrated environment for modeling disturbance
mechanisms, structural systems, optical components, and control systems that tightly couple to
determine end-to-end performance.

DOCS is a system initially developed
for modeling and optimizing complex optomechanical controlled systems
|
ACCOMPLISHMENTS
- The DOCS Phase II SBIR demonstrated the ability to perform
fully integrated system performance predictions on realistic sized systems (thousands of modes,
hundreds of outputs, and tens of inputs).
- The DOCS parameterization was used to perform
sensitivity studies and optimization of the fully integrated system design models.
- DOCS tracks and stores data flow of an analysis,
allowing the user to graphically visualize the relationship between analysis inputs and outputs.
|
COMMERCIALIZATION
- The software is currently being sold
under the name DOCSĀ® Toolbox.
- The primary target market is the aerospace industry,
and in particular the next generation of space-based observatories. In addition, it has found
a ready market in the ground-based observatory community.
- The DOCS Toolbox is currently technically mature enough for
commercial sale to its target market.
- The product is being sold commercially by Nightsky
Systems, Inc., Raleigh NC, a spin-off that was formed specifically to market the toolbox.

GOVERNMENT/SCIENCE
APPLICATIONS
- DOCS is designed to enable jitter analysis (including
redesign) and is suitable for NASA missions like JWST, TPF Coronagraph, and SDO
- For JWST and TPF, DOCS is being used to simulate the
performance of alternative designs and perform parametric analysis in order to set requirements for
structures (stiffness and damping), vibration isolation stiffness), and mechanisms that act as
disturbance sources.
- DOCS is currently mature enough for injection into
NASA missions like LISA and GOES. Planned future capabilities will increase its utility to other
missions (robotics and advanced planetary exploration).
