ABSTRACT

Terahertz imaging holds great potential in the field of security inspection. To meet this demand, this paper designs and constructs a passive terahertz real-time imaging system based on a MKID (Microwave Kinetic Inductance Detector) array and a spatial resolution layer. The system consists of an MKID detector array module, a spatial resolution layer module, a microwave signal coupling and amplification module, a signal mixing and acquisition module, an image reconstruction and processing module, a THz wave source and calibration module, a cryogenic superconducting module, and a microwave signal source and excitation module. Through the design of the MKID detector array, this paper enables the detection of the full frequency band of terahertz waves, significantly improving the sensitivity and accuracy of the detection system. By introducing the spatial resolution layer, spatial information is converted into time-domain signals, thus achieving spatial imaging of terahertz waves and enhancing the spatial resolution of the system. By adopting a digital acquisition system and fast signal processing algorithms, real-time acquisition and analysis of signals can be realized, further enhancing the real-time performance of the system.
