Real-time THz camera
The THz camera is comprised of a high resistivity silicon lens, a 80×64 focal plane array for image formation, ultra-fast diodes for THz signal detection, and a read-out circuit that collects DC signals from more than 5,000 antenna pixels. The camera can “see” in the 0.6-1.1 THz band at a 10 Hz frame-rate. Higher rates are achievable but with lower dynamic range.

Non-contact Measurements of mmWave and THz devices, circuits, and materials
A novel testbed that allows S-parameter measurements without contacting the device under test and without residing to expensive and fragile contact probes.
