In the last several decades, glow discharge detectors (GDD) have been utilized to detect
microwave radiation. Recently, these detectors were used to study higher frequencies within …

Development of focal plane arrays (FPAs) for mm wavelength and THz radiation is
presented in this paper. The FPA is based upon inexpensive neon indicator lamp Glow …

We present an inexpensive technique to obtain a three-dimensional (3D) millimeter wave
(MMW) and terahertz (THz) image using upconversion. In this work we describe and …

Based on the phenomenon that the incident terahertz (THz) radiation can increase the
discharge current and luminescent intensity of a glow discharge detector (GDD), the …

We present a high-sensitivity technique for time-resolved imaging of millimeter waves
(MMWs) using the visible continuum (VC) from the positive column (PC) of a medium …

The plasma medium, created inside the neon indicator lamp, enables the detection of a wide
wavelength range of differential or modulated EM signals. The interaction between the …

Inexpensive millimeter-wavelength (MMW) optical digital imaging raises a challenge of
evaluating the imaging performance and image quality because of the large electromagnetic …

Generally, glow-discharge detectors (GDD), acting on miniature neon indicator lamps, and
Schottky diode detectors serve as efficient, fast, and room-temperature millimeter wave …

Terahertz radiation impinging on a lit neon tube causes additional ionization of the
encapsulated gas. As a result, the electrical current flowing between the electrodes …

Applications of millimeter waves (MMWs), especially MMW imaging, are required in
medicine, homeland security, communication, and space technology. The lack of a fast and …
