Abstract
A novel concept towards pervasively available low-cost infrared thermal imaging system lunched on a mobile phone (MTIS) was proposed and demonstrated in this article. Through digestion on the evolutional development of milestone technologies in the area, it can be found that the portable and low-cost design would become the main stream of thermal imager for civilian purposes. As a representative trial towards this important goal, a MTIS consisting of a thermal infrared module (TIM) and mobile phone with embedded exclusive software (IRAPP) was presented. The basic strategy for the TIM construction is illustrated, including sensor adoption and optical specification. The user-oriented software was developed in the Android environment by considering its popularity and expandability. Computational algorithms with non-uniformity correction and scene-change detection are established to optimize the imaging quality and efficiency of TIM. The performance experiments and analysis indicated that the currently available detective distance for the MTIS is about 29 m. Furthermore, some family-targeted utilization enabled by MTIS was also outlined, such as sudden infant death syndrome (SIDS) prevention, etc. This work suggests a ubiquitous way of significantly extending thermal infrared image into rather wide areas especially health care in the coming time.
Highlights
Along with the growth of modern science, the thermal infrared imaging system is quickly emerging as an ever-powerful solution with diverse capabilities to detect temperature
Aiming to develop a pervasively available thermal imager, here we demonstrated a novel concept of low-cost thermal imager launched on the mobile phone, the MTIS
The whole architecture is built on a wireless network with a Wi-Fi router, and the mobile phone plays the role of the console in the control unit (Figure 2)
Summary
Along with the growth of modern science, the thermal infrared imaging system is quickly emerging as an ever-powerful solution with diverse capabilities to detect temperature. Such measurements were often performed using thermometers, thermocouples, and resistance temperature detectors (RTD). The thermal imager allows for an outstanding nondestructive temperature measurement in many complex situations. This feature makes the utilization of such devices rather competitive with quite a few other methods, which promises its profound impact in many coming practices
