Sofradir, a manufacturer of advanced infrared detectors, will give four presentations at next week’s SPIE Defense & Security 2008 in Orlando, Fla. The sessions will cover emerging trends in mercury telluride cadmium (MCT/HgCdTe) IR detectors.
Different semiconductor compound materials are used for cooled infrared imaging systems. Sofradir has pioneered MCT technology for both its second-generation and 2.5-generation IR detectors. Its high-class IR imaging systems are widely used in military and space applications that observe the environment, as well as target hot objects, such as rockets and vehicle motors.
The company is moving to third-generation MCT IR detectors that offer improved identification (dual-waveband), compactness, and reduced cost. Sofradir is collaborating with CEA-Leti, an international technology research center, on new technologies in these areas. The presentations at the SPIE look at these developments.
The presentations include:
- “IR detector design and approach for tactical applications with high reliability without maintenance;”
- “State-of-the-art of mass production: challenges for low-cost and application benefits of high-performance small-pitch IR detectors;”
- “Advanced HgCdTe FPAs and Applications;” and
- “Advanced ROICs design associated with HgCdTe technology.”
“We are focusing on reducing the pixel pitch and enhancing the reliability of our 2.5- and third-generation cooled IR detectors, as we and our customers believe they provide a high-performance, cost-effective solution for improved detection and identification at longer-range and in adverse weather conditions,” said Phillipe Tribolet, vice president of R&D at Sofradir. “Every year, this SPIE forum acts as a melting pot for new ideas and knowledge that push forward the frontiers of technology and we are glad to be a part of this.”
