Broadband Bendable Terahertz Camera For Built-In Infrastructure Sensor

We present a broadband bendable THz camera, composed of a free-standing carbon nanotube film array, which is intended for an built-in infrastructure sensor. As advantages over conventional solid-state THz sensors, our bendable THz camera can be fabricated through simple and low-cost processes and can simplify optical/electrical measurement systems, which enables us to mount the sensor on objects regardless of their shapes, sizes, and locations. We demonstrate the use of our novel THz camera for real-time nondestructive imaging of industrial products, indicating possibilities of one of the powerful components such as built-in/wearable THz sensors for future imaging and remote sensing.
