Journal ArticleDOI
Effects of aerosol forward scatter on the long- and short-exposure atmospheric coherence diameter
TL;DR: In this paper, an experimental investigation of the atmospheric coherence diameter is presented in order to examine the relative effects of turbulence and aerosol forward scattering, and it is shown that aerosols affect light coherence identically for both short and long exposures.
Journal ArticleDOI
Heterodyne Detection by Miniature Neon Indicator Lamp Glow Discharge Detectors
TL;DR: In this article, the authors compared the performance of GDDs in direct detection to GDD devices in heterodyne detection at 10 GHz and 300 GHz, and showed that GDD is almost two orders of magnitude more sensitive than direct detection, and in general sensitivity is inversely proportional to increasing local oscillator power.
Journal ArticleDOI
W-Band Chirp Radar Mock-Up Using a Glow Discharge Detector
TL;DR: In this paper, a proof of concept of chirp/FMCW radar detection using a very inexpensive glow discharge detectors (GDDs) in the W-band regime is demonstrated experimentally.
Journal ArticleDOI
Non-Kolmogorov atmospheric turbulence and optical signal propagation
TL;DR: In this article, the effect of non-Kolmogorov behavior of turbulence in various scales on the characteristics of electromagnetic waves propagation through a turbulent atmosphere on the example of certain atmospheric experiments is discussed.
Journal ArticleDOI
Heterodyne detection at 300 GHz using neon indicator lamp glow discharge detector.
TL;DR: A miniature neon indicator lamp, also known as a glow discharge detector (GDD), costing about 50 cents, was found to be an excellent room temperature terahertz radiation detector and preliminary results at 300 GHz showed better sensitivity by a factor of 20.
