Millimeter-wave–Infrared multi-wavelength computed tomography

Carbon nanotube (CNT) film-based sensors are attracting attention as a technology that enables ultra-broadband and multi-wavelength optical imaging. Here, we report on the achievement of nondestructive material identification and structural reconstruction of a three-dimensional object made of multilayered composite materials by combining wide-band multi-wavelength long-wavelength optical imaging using CNT film-type elements and computed tomography measurement, a typical example of computer vision technique.
