In recent years, terahertz imaging systems and techniques have been developed and have
gradually become a leading frontier field. With the advantages of low radiation and clothing …

With the strengthening of global anti-terrorist measures, it is increasingly important to
conduct security checks in public places to detect concealed objects carried by the human …

Real-time video-rate passive terahertz imaging systems are highly demanded for practical
applications, especially in security checking. Here, we demonstrate a passive video-rate …

The passive terahertz (THz) detection on objects concealed under clothing is quite
challenging due to the heavy noise interference. In this paper, an active‐contour‐based self …

Detection of integrated circuit (IC) defects is vital in IC manufacturing. Traditional defect
detection methods have relied on scanning electron microscopy and X-ray imaging …

As a harmless detection method, terahertz has become a new trend in security detection.
However, there are inherent problems such as the low quality of the images collected by …

Effective detection of concealed dangerous equipment is a critical need to protect
people'security in crowd public situations. Terahertz (THz) technology is ideally suited for …

Passive terahertz (THz) systems can perform the perspective imaging of objects concealed
underneath clothing on the human body without a radiometric emitter. In this study, a linear …

Abstract The physics of Terahertz (THz) technology is the electromagnetic (EM) spectrum
band between the infrared and the microwave band with frequencies of about 0.1 to 30 THz …

The automatic extraction of the targets in which we are interested from a given image is the
fundamental of the automatic detection and identification for security screening systems …
