Intelligent Light is seeking partners with whom to collaborate on recently completed research into visualizing unsteady turbulent flows. Through a Phase II STTR from AFOSR, researchers at IL developed a technique whereby the system can be trained to find features like turbulent vortices and then track those feature statistically over time.

Those interested in collaborating on this research should contact IL by emailing
