Although visualization technique based on terahertz (THz) frequency region shows significant potentials for nondestructive, noncontact, and noninvasive imaging applications in various industrial sectors, investigation of ubiquitous measurement system is highly demanded for practical usage. In this work, we developed a novel type portable 360^o all-around view photo-thermal camera by integrating flexible carbon nanotube (CNT) film THz array scanners with miniature photo sources. In addition, we successfully demonstrated a ubiquitous nondestructive all-around view monitoring of a columnar object by a usage of the presented device module, which is highly adoptable for a portable multi-view inspection system of poorly accessible infrastructure facilities.
