Abstract
This paper reports a novel thermal imaging device using a photo-patternable temperature sensitive paint (PTSP). The PTSP, which has the temperature dependence of luminescence, is used as both structural and temperature sensing materials. The self-suspended PTSP structures are heated up by the radiation from an observation object, and the temperature change is converted to the intensity of luminescence, which can be measured by a CCD camera. A transfer method was employed to prevent the self-suspended structures from sticking to the device substrate. The thermal image of a black body object heated at 700℃ was successfully obtained. The proposed thermal imaging device is applicable to low-cost thermal imaging applications such as home-security and fire detection/extinction systems.
