DISP Projects

AWARE Wide Field of View Imaging

The AWARE Wide Field of View Imaging Project uses a multi-scale design techniqued to develop large format imaging systems that significantly exceed the SWAP constraints of conventional imaging systems. Through the use of mononcentric optical designs and using microcameras as a general optical processing unit, we are developing designs that scale from one gigapixel to 40 gigapixels and greater.

Multi-frame Coded Aperture Snapshot Spectral Imaging

Multiframe Coded Aperture Spectral Imagers are based off the CASSI system, but modulate the coded aperture between every snapshot to increase the rank of the system matrix. For static scenes, this greatly enhances the reconstruction quality with only slight computational and acquistion overhead.

Millimeter Wave and Terahertz Imaging

Millimeter Wave and Terahertz Imaging is of great interest for its large penetration depth at non-ionizing energy levels. Current projects in millimeter wave consist of compressive holography and interferometric synthetic aperture imaging.

Coded Aperture X-ray Imaging

Coded aperture x-ray imaging enables molecular specificity and measurement efficiency in x-ray tomography systems.

 

 

Computational Mass Spectroscopy

As described in US Patent 7,399,957, DISP is building compressive mass spectroscopy systems.

 

Knowledge Enhanced Exapixel Photography

Under the DARPA Knowledge Enhanced Compressive Measurement (KECoM) program, DISP is developing image space coding strategies to radically reduce electronic power cost in high pixel count cameras. Preliminary results under this program are described in Coding for Compressive Focal Tomography by D. J. Brady and D. L. Marks.

 
           
DISP has been a unit of the Fitzpatrick Center, the Department of Electrical and Computer Engineering and the Pratt School of Engineering at Duke University since January 2001. From 1990 until 2001, DISP was the photonics systems group of the Beckman Institute at the University of Illinois.
