Voxtel Inc. Wins DOD Contract for Advanced Detector Technology Program

Will Develop High-Resolution Laser Ranging Camera
Portland, OR. — July 13, 2003— Voxtel Inc. a leading provider of advanced infrared and low light level imaging technology, today announced that it has received a U.S. Air Force contract for the first phase of a 36-month program to develop a high bandwidth, low noise, focal plane array and camera for laser ranging.

Voxtel’s approach, unique in its sensitivity and range resolution, will be accomplished with a high performance, near-infrared (NIR) avalanche photodiode (APD) focal plane array and camera. The Department of Defense Missile Defense Agency is providing the funding under a contract managed by the Air Force. “By leveraging Voxtel’s expertise and investment in high speed, low noise integrated circuits and sensors, for the first time, range imaging will be possible with a resolution of better than 20-cm at distances of several thousand kilometers,” said Mr. George Williams, President, Voxtel Inc. During the contract, Voxtel will be manufacturing APD cameras capable of sensing fewer than 10 photons within one billionth of a second.

The Phase 1 contract spans a six-month period during which Voxtel will demonstrate its technical approaches for the Advanced Detector. If fully executed through Phase 3 of the program, the Voxtel contract will total $5.5M and will culminate in the delivery of an advanced laser ranging camera to the Air Force.

The research funding will support the development of Voxtel’s commercial product development of infrared avalanche photodiode products, which are high speed detectors capable of detecting single photons, the primary particles of light, and are used for a broad range of applications including DNA sequencing, biomedical imaging, cancer screening, telecommunications, laser radar and astronomy.
