International Journal of Infrared and Millimeter Waves, 1998
The paper describes a band-splitting filter or diplexer, which splits the incoming spectrum into the sub-bands 120-139 GHz and 141-158 GHz. This diplexer is intended to separate the electron cyclotron emission of a magnetically confined plasma into two subbands and to feed two independent heterodyne radiometers.

Millimeter-wave-detected, millimeter-wave optical polarization spectroscopy
The Journal of Chemical Physics, 2005We report a new form of microwave optical double-resonance spectroscopy called millimeter-wave-detected, millimeter-wave optical polarization spectroscopy (mmOPS). In contrast to other forms of polarization spectroscopy, in which the polarization rotation of optical beams is detected, the mmOPS technique is based on the polarization rotation of ...

Laser-Millimeter Wave Techniques
Applied Optics, 1971The use of millimeter techniques with lasers has resulted in the stabilization of a laser to an absolute frequency standard. Also, a high resolution infrared spectrometer with the characteristics of a microwave spectrometer has been developed.

Millimeter-Wave Imaging Sensor
SPIE Proceedings, 1986A dual polarized 3-mm radiometer system, with a mechanically scanned antenna, has been built for use on a small aircraft or RPV to produce near real-time moderate resolution (0.5°) images of the ground. One of the main advantages of this passive imaging sensor is that it is able to provide surveillance information through clouds, smoke, and dust when ...

Millimeter-Wave Integrated Circuits
IEEE Transactions on Microwave Theory and Techniques, 1968Monolithic millimeter-wave integrated circuits have been designed and fabricated on semi-insulating GaAs substrates using microstrip transmission lines. Circuits using hybrid techniques have also been constructed on quartz and ceramics. This paper shows that microstrip-line integrated circuits are feasible at millimeter-wave frequencies.

Millimeter-wave radiometric imaging
International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990The capabilities of radiometric imaging of the environment with the German Aerospace Research Establishment (DLR) modular linescanner system are demonstrated. Efficient information enhancement algorithms have been shown to improve the data interpretation and evaluation.

Physics Today, 1950
Electromagnetic radiation, an inexhaustable natural resource, plays an extremely important part in modern technology and living. We use very short wavelength radiation, that is, x-rays, in searching for otherwise hidden defects. We use longer wavelength radiation, that is, light, to see by. We can take photographs with infrared radiation.
