[22p-B203-18] Silhouette-based non-destructive 3D reconstruction with broadband carbon nanotube photo-sensors
Keywords:carbon nanotube, photovoltaic effect, non-destructive inspection
Non-destructive testing technology is indispensable in the industry. In addition, demand for high-precision internal inspections of 3D-structured objects is increasing, and inspection techniques using electromagnetic waves attracts significant attention. Although conventional non-destructive inspection utilizes X-ray, their hazardous configurations associated with invasiveness need to be addressed. On the other hand, photo-sensing in broadband ranging from infrared (IR) to millimeter-waves (MMW), which non-invasively exhibits high transmittance, potentially solves the above problem. In these bands, CNT films are well known for their highly efficient absorption. Herein, this study utilizes CNTs photo-thermal broadband sensors for IR–MMW imaging of three-dimensional objects. As a result, the combination of the multi-wavelengths imaging and typical silhouette-based 3D reconstruction techniques enables non-destructive inspection of multi-layered objects.
