Astronomical Research Spawns Detector Innovation

Facebook X LinkedIn Email
The need for space-quality instrumentation for the James Webb Space Telescope has resulted in innovative detectors that will benefit many ground-based efforts well before the telescope's launch.

From the middle of the Pacific, Gerard Luppino has a good view of the future and of the past. Luppino, an astronomy professor at the University of Hawaii’s Institute of Astronomy in Honolulu, has access to the optical and infrared observatories clustered on the 13,800-foot summit of the dormant volcano Mauna Kea. Those instruments allow him to probe deep into the past. Researchers at Lincoln Laboratory at Massachusetts Institute of Technology built the eight 2k × 4k-pixel CCDs that make up this 8k × 8k optical CCD mosaic. The pixel size is 15 μm, and the overall array measures 122...Read full article
