Proceedings ArticleDOI
3D Millimeter Wave imaging system using chirp radar and Glow Discharge Detector pixel
TL;DR: In this paper, a unique quasi-optical set up and advanced detection methods using the Glow Discharge Detector (GDD) Focal Plane Array (FPA) are intended to build the 3D MMW imaging system.
Proceedings ArticleDOI
Upconversion of millimeter waves to visible waves: inexpensive focal plane array MMW imaging and ultra-fast MMW wireless communication
TL;DR: In this paper, the authors reported an optical means of detection which is manifested as an increase in light intensity emitted by the lamps caused by the incident MMW/THz wave, and measured using optical detectors such as avalanche photodiodes or CCD or CMOS cameras focused on the glow discharge detectors (GDD) to measure change in emitted light intensity.
Proceedings ArticleDOI
Influence of aerosols and optical turbulence strength on laser beam widening in the atmosphere
TL;DR: In this paper, the atmospheric aerosol contributions to laser beam widening for a horizontal propagation path at various elevations is estimated and compared with beam widening caused by turbulence, and it is shown that the impact of atmospheric aerosols is significant.
Proceedings ArticleDOI

H. Joseph,Norman S. Kopeika,Amir Abramovich,A. Akram,A. Akram,Assaf Levanon,Assaf Levanon,Daniel Rozban,Daniel Rozban +8 more
TL;DR: In this paper, a miniature neon display lamp acting as a Glow Discharge Detector (GDD) is compared to the performance of GDDs in direct detection at 10 GHz and at 300 GHz with a low power source.
Journal ArticleDOI
Observation of light detection by glass–metal seals: their influence on measurements involving discharges as light detectors and the possibility of optical-fiber light detectors
TL;DR: In this paper, it is reported that glass-metal seals give rise to photocurrents as a result of light illumination, and the detection performance is of the order of 10 mA·W−1.
