CASISCASIS History
Signal and image processing, along with related disciplines, have had significant mission impact at LLNL through the decades

Signal and Image Processing at LLNL — The 1970s

Image Processing Lab
A CASIS staff engineer is here seen working in the Image Processing Lab on the then-new interactive digital processing system. Image enhancement applications included flash X-ray diagnostics and biomedical imaging.
“Information processing research is being conducted in digital signal processing, image analysis, applied estimation and detection theory, computer-aided design, … developing national energy models, and solving complex controls problems.”

Signal and Image Processing at LLNL — The 1980s

NDE
CASIS researchers applied non-destructive evaluation techniques for radioactive waste barrel inspection and other Department of Energy needs; here, array techniques coupled with laser interferometry reveal flaws in a material
Signal and image processors pioneered diagnostic techniques for analyzing the performance of massive-scale laser experiments such as Shiva and Nova
Nova Diagnostics
AVLIS
Controls expertise allowed for the careful alignment required for Atomic Vapor Laser Isotope Separation (AVLIS)
Laboratory image processing experts developed View, a fourth-generation programming language that was one of the first image processing computing environments

Signal and Image Processing at LLNL — The 1990s

Space
CASIS researchers participated in the successful Clementine Moon mapping mission in 1993, resulting in a complete mapping of the lunar surface and the detection of ice near the north and south poles
Parametric signal processing techniques were employed to extract and enhance critical features to classify the condition of prosthetic heart valves
Heart Valves
Guide Star
Adaptive optics controls and image processing enable the Laser Guide Star, sharply increasing resolution for astronomical imaging

Signal and Image Processing at LLNL — The 2000s

PEREGRINE
CASIS researchers helped develop the innovative PEREGRINE™ system, which was FDA-approved to perform accurate dose calculations for all types of radiation therapy
Model-based signal processing joined with chemistry and physics enabled these laser cantilever detectors
Cantilevers
Target Positioner
Signal & image processing and controls expertise enable positioning of the target at the National Ignition Facility with an accuracy finer than the thickness of a human hair

Signal and Image Processing at LLNL — The 2010s

GPI
Adaptive Optics techniques serve a critical role for the Gemini Planet Imager, part of an international search for exosolar planets from the Gemini South telescope in Chile
Array processing techniques were at the heart of this ground-penetrating radar system, developed for real-time buried hazard detection
GPR
Network Graph
Machine learning approaches have enabled detection of anomalous behavior in computer networks, even at very large scale
