Despite enormous advances in non-destructive imaging in the field of accessible electromagnetic
"The transition from manned to roboticcontrol can make operations such as checking power lines disconnected and examining confined conditions safer and more sustainable, ”explains Professor Yukio Kavano of Tokyo University of Technology and Chuo University, who conducts extensive research in terahertz EM wavelengths.
Professor Kavanaugh and colleagues at Tokyo Techdeveloped a robotic broadband (broadband) photomonitoring platform equipped with a light source and an imager that can operate regardless of location and switch between reflective and transmissive sensing.
In the proposed module, scientists used thinfilms of physically and chemically enriched carbon nanotubes (CNTs) as uncooled imaging sheets. They used the "photothermoelectric effect" to convert light into an electrical signal through thermoelectric conversion.
Thanks to its excellent absorption properties inover a wide range of wavelengths, CNTs showed broadband sensitivity. In addition, the imaging sheet allowed stereoscopic sensing operation in both reflective and transmissive modes, thereby enabling the inspection of multiple curved objects such as beverage bottles, water pipes, and gas pipes. By detecting local changes in signals, scientists were able to identify tiny defects in these structures that would otherwise be invisible.
Finally, they achieved photomonitoring with a review in360 ° using a compact sensor module integrated with a light source, and implemented the same in a multi-axis movable robot arm that performed high-speed photomonitoring of a defective miniature model of a winding automobile bridge.
