Investigations of coal combustion using a thermographic method

Combustion and Flame, 1982
The authors describe a novel infrared technique for observing coal combustion, including the initial, low temperature reactions. An AGA 680 thermovision system records total radiation in the wavelength range 2-5.6 MUm: the temperature can be measured at frequencies up to 1600/sec. The combustion of anthracite and of lignite have been investigated.

On Methods for Shape Correction and Reconstruction in Thermographic NDE

1994
In this paper, various methods are proposed to correct distorted infrared images recorded over curved specimens. This problem is particularly important in thermal inspection applications, in order to avoid misinterpretation of the results. In the paper four methods are discussed: point source heating, video thermal stereovision, direct IR image ...

Data-processing method for standardization of thermographic diagnosis

Proceedings of the 22nd Annual International Conference of the IEEE Engineering in Medicine and Biology Society (Cat. No.00CH37143), 2002
In previous papers, areas of temperature change were analyzed using the average temperature of frames or the differences between different shaped thermograms of the affected side and the normal side. But, by this method, it is impossible to accurately evaluate temperature differences.

A method of concurrent thermographic–photographic visualization of flow boiling in a minichannel

Experimental Thermal and Fluid Science, 2010
A method is developed to capture the distribution of surface temperature while simultaneously imaging the bubble motions in diabatic flow boiling in a horizontal minichannel. Liquid crystal thermography is used to obtain highly resolved surface temperature measurements on the uniformly heated upper surface of the channel.

Correction of the Temperature of Biological Objects in Thermographic Methods

Journal of Applied Spectroscopy, 2019
The proposed correction allows to refine the surface temperature determined by a standard noninvasive thermographic method based on IR images for the human skin with a nonuniform in depth temperature distribution. The nonuniformity is due to the biophysical necessity of normal functioning of the organism, as well as to a possible presence of ...

Feasibility of a Thermographic Method for Early Detection of Foot Disorders in Diabetes

Diabetes Technology & Therapeutics, 2009
Foot complications due to diabetes impose a major economic burden to society and loss of health-related quality of life for the patients. Early diagnosis and intensified preventive measures have proved useful to limit the incidence of foot ulcers and lower limb amputations in diabetes, and the development of new tools for early diagnosis has therefore ...

[Possibility of the thermographic method for detection of ischemic myocardium].

Kardiologiia, 2010
Thermography (TG) is used as a contact free method for investigation of the myocardium ischemic injury. In coronary bypass surgery without artificial blood circulation it is important to know how cessation of blood supply affects the myocardium. In experiments on working heart, TG allows monitoring temperature at the desired point of the epicardium ...
