DOD funds tiny cave camera and iris recognition technology for military, homeland security
Date:4/14/2010

g of Panoptes short for "Processing Arrays of Nyquist-limited Observations to Produce a Thin Electro-optic Sensor" to $5.5 million. The new applications have been dubbed AIM-CAMS, for "Active Illumination with Micro-mirror-arrays for Computational Adaptive Multi-resolution Sensing," and Smart-Iris, for "SMU's Multi-resolution Adaptive Roving Task-specific Iris Recognition Imaging System."

For a video and links to more information about Panoptes see http://blog.smu.edu/research/2010/03/dod_funding_drone_cameras_and.html#more.

Hi-resolution "eyes" in caves, urban alleys

Panoptes initially was designed for military aerial drones and combat helmet cameras for use in daylight environments. The technology produces sharp, clear images without the size and weight of a conventional camera system because it doesn't rely on a large, bulky, curved lens for high-resolution images.

Instead, arrays of agile and precisely controlled microelectromechanical system (MEMS) mirrors are integrated with low-resolution sub-imagers on a silicon base for the purpose of sampling a wide field of view. The analog steerable MEMS mirrors adaptively redirect plexiglas sub-imagers to zoom in on regions of interest. The captured images are stored in an onboard computer and restored to high-resolution by an information theory-based super-resolution algorithm.

The sub-imagers are tiny off-axis-shaped paraboloids, fabricated using injection molding. At 8 millimeters by 5.7 millimeters by 4 millimeters, the sub-imagers have an effective focal length of 4 millimeters and are tiny enough to fit on the surface of a small coin. The honeycomb-shaped micro mirror array comprises 61 hexagonal mirrors, each with three actuators to mechanically move and control the mirrors. The usable circular aperture, the opening through which light travels, is 3.9 millimeters in diame
