The novel concept of the security system based on THz Bessel beams is offered. The system is based on a novel THz diffractive optics for scanning the person without the application of THz laser and on a sensitive scheme for the detection of the reflected and scattered THz radiation. The development of enabling technology, namely, sensitive detector arrays and Millimeter wave-THz diffractive optics, will allow building compact, easy-to-use millimeter wave-THz imaging systems without expensive cost THz laser. The scanning properties of diffractive optics for Bessel beam are investigated.
