This paper proposes and validates a novel simulation for thermal non-destructive characterization. An electro-thermal modelling of the sample is adapted for MATLAB-SIMULINK simulation. Though the technique is capable of considering any heat stimuli on an arbitrary sample, the special case of lock-in thermography (LT) with periodic heating is taken up for illustration. A mild-steel sample having...

Electrowetting (EW) involves the actuation of liquid droplets using electric fields and has been demonstrated as a powerful tool for initiating and controlling droplet-based microfluidic operations such as droplet transport, generation, splitting, merging and mixing. The heat transfer resulting from EW-induced droplet actuation has, however, remained largely unexplored owing to several challeng...

This work presents collaboration between electronics industry and University aimed to develop novel power cycling methodology combined with IR thermography for quality and reliability studies of microelectronic assemblies. For this purpose an array of programmable Thermo Electric Converters (TEC) was designed and constructed [1]. The array provides possibility of introduction of controlled anis...

This paper introduces the development of prototype robot based thermography measuring system and a new concept for higher robot position accuracy for industrial applications. The developed thermography system is mounted at the end-effector of an industrial robot. Furthermore, a platform for offline programming is introduced, which enables the identification of measurement positions and the opti...

Foils coated with specific cholesterol esters indicate differences in temperature by changes in color. When these foils are placed on the skin, the skin temperature measured is related to the perfusion provided by the vessels supplying this area of the skin. A group of 300 patients were examined simultaneously with plate thermography and directional Doppler sonography in order to detect obstruc...

Ground Penetrating Radar (GPR) and airborne thermography have been used for the location of buried spring barrier ponds and for the investigation of the shallow subsoil. Thermography has been selected for its ability to cover a wide area in a short time, the GPR has been chosen for the ability to distinguish, in great detail the presence of permeable layers composing the subsoil. Very positive ...

0. Abstract In this paper we propose a simple enhancing protocol for pulsed infrared thermography. The method is based on stimulating the specimen with two heating pulses separated by a short time interval delta. This approach was tested on several specimens of low and high thermal diffusivity and showed to provide higher thermal contrasts when an optimum interval delta is chosen. The observed ...
