it has been demonstrated that anxiety is accompanied by significant warm up in the periorbital area. this warm up was attributed to the increased blood circulation in the area around the eyes. the whole pattern makes physiological and evolutionary sense since it represents a mechanism to facilitate rapid eye movements during preparedness for fight. this increased blood flow dissipates convectiv...

In this paper, we used a freeform lens in a long-wave, un-cooled, refractive infrared (IR) thermal imager and present the design strategy and test results. This optical system is composed of only one freeform lens and several spheres. It can correct the distortion issue inherent to wide field-of-view systems more effectively, and achieve a better thermal imaging performance simultaneously compa...

The discovery of infrared radiation by William Herschel in 1800 led to John Herschel’s study of solar radiation that he imaged by evaporography. This he termed a thermogram. The measurement of temperature in medicine advanced with Dr Carl Wunderlich, who showed the significance of the use of temperature measurements for diagnosis of fever and for monitoring the course of temperature in relation...

We report on mid-infrared imaging of hot cores performed with SpectroCam– 10 and TIMMI2. The observations aimed at the detection of thermal emission presumably associated with the hot cores. Mid-infrared flux measurements are required to improve the luminosity and optical depth estimates for these sources. Results are presented for W3(H2O), G9.62+0.19, G10.47+0.03, and the possible hot core can...

This paper proposed an efficient omnidirectional thermal imaging surveillance system featuring trespasser and faint detection. In this thermal imaging system, the omnidirectional scenes in a monitored site such as old folks home, nursing home, hospital etc. are first captured using a thermal camera attached to a custom made hyperbolic IR (infrared radiation) reflected mirror. The captured scene...

The value of Infrared thermal imaging (ITI) is limited to evaluation of neurovascular dysfunction. It provides indispensable information regarding neuropathic pain due to perivascular microcirculatory sympathetic dysfunction. ITI records superficial, and deep temperature changes. The bilateral cervical cord temperature modulation demands careful clinical correlation. The ITI is an objective gui...

OBJECTIVE To determine the usefulness of medical infrared thermal imaging (MITI) as a screening tool for hyperthyroidism in cats, evaluate the need for hair clipping over the ventral aspect of the neck to achieve optimal images, and determine whether there is a change in thermal patterns at 1 and 3 months after radioactive sodium iodide I 131 treatment. ANIMALS 17 cats with and 12 control cat...
