Low cost millimetre wave camera imaging up to 140GHz

A millimetre wave (nun-wave) camera that combines a novel mechanical scanning method with a sparse array of receivers has been demonstrated. The camera provides frequency independent, near real-time raster images with high efficiency and can be used with either active illumination or in a passive mode. Working with 77GH2, 94GHz and 140GHz receivers, the camera has provided high-quality, fast-capture images.
