Infrared thermal imaging system on a mobile phone.

Lee FF, Chen F, Liu J - Sensors (Basel) (2015)

Bottom Line: 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.The performance experiments and analysis indicated that the currently available detective distance for the MTIS is about 29 m.This work suggests a ubiquitous way of significantly extending thermal infrared image into rather wide areas especially health care in the coming time.

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.

Mentions: In order to further evaluate the performance of MTIS, we additionally performed tests on several groups of thermal pattern of the same persons by using MTIS. Each group indicates the thermal imaging results at different distances from the MTIS, and contains two kinds of body position patterns, sitting and crouched, as shown in Figure 7a,b, respectively. Then, we solicited 14 volunteers for a recognition experiment. After watching the pattern, each volunteer individually answers the question as which kind of body position is in the thermal image.
