Recent advances in THz detection with the use of CMOS technology have shown that this option has the potential to be a leading method of producing low-cost THz sensors with integrated readout systems. This review paper, based on authors’ years of experience, presents strengths and weaknesses of this solution. The article gives examples of some hints, regarding radiation coupling and readout systems. It shows that silicon CMOS technology is well adapted to the production of inexpensive imaging systems for sub-THz frequencies. As an example paper presents the demonstrator of a multipixel Si-CMOS THz spectroscopic system allowing for chemical identification of lactose. The THz detectors embedded in this system were manufactured using the CMOS process.

We report on construction and evaluation of a moving wirelessly-controlled thermal phantom for testing cameras working in the terahertz range (0.1-3.0THz). A terahertz camera operating at 0.25 THz and a standard thermal camera were used for tests. We compared the images taken for the phantom and a man and we obtained satisfactory similarities both for naked as well as dressed objects with hidden items (guns, knives, bombs). The temperature stability of the phantom is also sufficient for evaluation of the cameras.

Przedstawiono konstrukcję i badania ruchomego zdalnie sterowanego fantomu termalnego człowieka opracowanego do testów kamer terahercowych (0,1-3,0THz). Do testów użyto kamery terahercowej pracującej w zakresie 0,25THz i kamery termalnej. Uzyskano bardzo dobre podobieństwo pomiędzy obrazami w zakresie THz dla człowieka oraz fantomu oraz satysfakcjonującą stabilność termalną fantomu.

In this paper we report on measurement of spectra of commonly applied explosives, some materials which can be used for manufacture of explosive and THz simulants of explosives in transmission mode. Substances were prepared as pellets, and the measurements were performed using the Time Domain Spectroscopy system in the range 0.1–3.0 THz.
