New detector technology

A new generation of imaging detectors with low-noise and high-speed capabilities may transform imaging applications on NASA space missions, impact biomedical imaging and aid in homeland defence.

Rochester Institute of Technology and the University of Rochester recently won $847,000 from NASA’s Astronomy Physics Research and Analysis program to build and test a detector that will capture sharper images and consume less power than technology currently in use.

According to RIT, the new imaging sensor, which will function at wavelengths spanning from ultraviolet to mid-infrared, will be able to operate reliably in the harsh radiation environment of space.

'These benefits will lead to lower mission cost and greater scientific productivity,' said Donald Figer, director of the Rochester Imaging Detector Laboratory at RIT and lead scientist on the project. The team also includes Zoran Ninkov from RIT and Zeljko Ignjatovic from the University of Rochester.

The new detector is based on a technology created by Ignjatovic and his colleagues at the UR. It will shrink the required hardware on NASA planetary missions from the size of a crate weighing tens of pounds to a tiny thumb-sized chip. It also will enhance images captured by ground telescopes that will rival those from orbiting telescopes, like the Hubble Space Telescope.
