Abstract :
A multiple frequency heterodyne imaging system has been established and is now being used to study a range of biological and material samples in the submillimeter wave frequency regime. Advantages of this imaging system include signal-to-noise >80 dB from 200 to 700 GHz, true magnitude and phase, simple frequency shifting, dual simultaneous frequency measurements, and transportable transmit and receive heads. This paper describes the test system and presents some examples of its use for biological and space science applications.
