“…where B = 1 MHz is bandwidth of the LTF [26]. Note that the GDD modulation bandwidth is very high, on the order of several GHz [12,18], attesting to the GDD speed of response. In these speed measurements, speed was limited by the optoelectronic detector and not by the GDD plasma.…”

“…The glow discharge detector (GDD) was found to be one of the typical MMW/THz radiation detectors [3,4,[6][7][8][9][10][11][12] and pixels in focal plane arrays [13][14][15][16][17][18] but is orders of magnitude less expensive compared to other known MMW/THz sensors [1]. This is particularly important for detector arrays as in imaging.…”

“…Two detection methods of the GDD were investigated: the first is the electrical current method [3,4,[6][7][8][9][10][11], in which the changes in the bias current of the GDD due to incident MMW/THz radiation were measured. The second is the optical up-conversion method [12,18], in which the changes in the emitted light of the GDD due to the incident MMW/THz radiation were measured using a standard optical sensor.…”

Performance enhancement of a very inexpensive millimeter-wave (MMW)/terahertz (THz) sensor for MMW/THz imaging systems is experimentally demonstrated in this study. The MMW sensor is composed of a glow discharge detector (GDD) and a light-to-frequency (LTF) converter combination. The experimental results given in this study show an improvement in the performance parameters of the detector element, such as the minimum detectable signal, as well as the signal to noise ratio (SNR) and the noise equivalent power (NEP), when a NIR long-pass filter was inserted between the GDD and the LTF combination. A detailed derivation of the NEP of this unique sensor is presented in this work. Based on this derivation and the experimental measurements, the NEP value was calculated.

“…In the upconversion method, some of the light emitted from the GDD does not arrive at the APD so we lose part of the signal intensity. The internal noise of the upconversion method is significantly lower than the internal noise of the electric detection . For high frequencies of MMW modulation, the optical method has higher responsivity …”

The terahertz gap (0.1‐10 THz) is an attractive frequency band for new applications. In wireless communication, it can serve as a high capacity link. The lack in use of that gap exists due to a lack of available commercial communications technology systems in that region. We have found that neon indicator lamps or glow discharge detectors (GDD) can be used as simple and very inexpensive detectors in that frequency gap. In modern modulation techniques, the signal phase should be recovered. This article is a proof of concept of detection of quadratic amplitude modulated millimeter‐wave signals by a GDD and photodiode using a heterodyne detection method.

The relatively high atmospheric propagation of millimeter-waves (MMW) was found to be one of the most critical reasons for the development of reliable sensors for MMW detection. According to previous research works, it has been already shown that incident MMW radiation on a glow discharge detector (GDD) can increase the discharge current. Hence, the electrical mode of detection can be employed to detect the presence of MMW radiation. In this article, a new design of a row detector using GDDs as pixel elements, and the influence of MMW incidence on GDD’s discharge current, were acquired using an elementary data acquisition (DAQ) platform. The DAQ system computes the averaged Fast Fourier Transform (FFT) spectrum of the time signal and returns the FFT results as magnitude based on the level of detection. An FFT-based signal acquisition proved to be a better alternative to the lock-in detection that was commonly used in MMW detection systems. This improved detection circuit provides enhanced noise filtering, thereby resulting in better MMW images within a short time. The overhead expense of the entire system is very low, as it can avoid lock-in amplifier stages that were previously used for signal enhancement. A scanning mechanism using a motorized translation stage (step motor) is involved to place and align the row detector in the image plane. The scanning can be carried out vertically to perform the imaging, by configuring the step motor after selecting the desired step size and position. A simplified version of the MMW detection circuit with a dedicated over-voltage protection facility is presented here. This made the detection system more stable and reliable during its operation. The MMW detection circuit demonstrated in this work was found to be a milestone to develop larger focal plane arrays (FPA) with very inexpensive sensor elements.
