“…In addition, the typical sensitivity and responsiveness of micro-bolometers is inherently lower than photon detectors. Despite these limitations, the recently introduced miniature thermal core printed circuit board mounted micro-bolometer based cameras [15], costing as little as 300 USD, has prompted the present investigation into their applicability for LIT. The small format and low cost of the thermal core, in combination with the embedded actuators proposed in the paper, offer a new methodology for LIT with the potential for permanent deployment on a structure and a route to thermography based structural health monitoring.…”
