Micro-thermal analysis combines the imaging capabilities of atomic force microscopy with the ability to characterise, with high spatial resolution, the thermal behaviour of materials. The conventional AFM tip is replaced by a miniature heater/thermometer which enables a surface to be visualised according to its response to the input of heat (in addition to measuring its topography). Areas of in...

Infrared thermography is used for measuring and analyzing physiological functions and pathology related to the body’s thermal homeostasis and temperature. This review provides an overview of the technological advantages of infrared imaging, with the focus on new advances in and opportunities for infrared imaging, as a reliable medical diagnostic tool. The review has four main parts. Firstly, a ...

Infrared scene projectors (IRSPs) are a critical laboratory tool for setup, testing and calibration of infrared imaging systems. These projectors create an infrared scene of precisely known characteristics. The projector typically uses a single chip infrared emitter array to produce actual infrared imagery. A promising device technology for building emitter arrays is infrared light emitting dio...

Biometrics is a technology used for measuring and analyzing a person's unique characteristics. Making a secure biometric system is not as easy as it might appear. The word biometrics is very often used as a synonym for the perfect security. Human Biometrics is now moving towards thermal imaging. Thermal imaging is simply the technique of using the heat given off by an object to produce an image...

The application of sensors encompasses many sectors of industry. In this paper, we outline different sensors – Raman distributed temperature sensor, sensor based on nano ferrofluids and MEMS based ultrasonic sensors. The development and application of these sensors for monitoring performance of systems and processes are discussed. Further, we also discuss the application of acoustic emission an...

This study aims at performing grain scaled energy balance in mechanically-loaded aluminum polycrystal specimen. Two complementary imaging techniques were used in order to investigate the so-called material thermomechanical behavior: Digital Image Correlation and InfraRed Thermography to investigate respectively the kinematic and the thermal response of the material and, combining these two tech...

We predict the existence of dusty disks and possibly CO planets around massive white dwarfs. We show that the thermal emission from these disks should be detectable in the infrared. The planets may also be detectable either by direct IR imaging, spectroscopy, or using the pulsations of the white dwarfs. Subject headings: white dwarfs—stars: planetary systems—accretion disks

Nanotechnology approaches offer the potential for creating new optical imaging agents with unique properties that enable uses such as combined molecular imaging and photo-thermal therapy. Ideal preparations should fluoresce in the near-infrared (NIR) region to ensure maximal tissue penetration depth along with minimal scattering and light absorption. Due to their unique photophysical properties...

non-invasive ultrasound surgeries such as high intensity focused ultrasound have been developed to treat tumors or to stop bleeding. in this technique, incorporation of a suitable imaging modality to monitor and control the treatments is essential so several imaging methods such as x-ray, magnetic resonance imaging and ultrasound imaging have been proposed to monitor the induced thermal lesions...
