The clinical significance of a burn depends on the percentage of total body involved and the depth of the burn. Hence a noninvasive method that is able to evaluate burn depth would be of great help in clinical evaluation. To this end, photoacoustic microscopy is used to determine the depth of acute thermal burns by imaging the total hemoglobin concentration in the blood that accumulates along t...

Lensless ghost imaging (LGI) with thermal light requires an equal length between the test and reference arms. When this condition is not met, the image becomes blurred. Here we propose an experimental scheme of LGI where the lengths of the two arms are not equal. Our experiment shows that when a glass rod is inserted into a longer arm, the clear image can be formed in the intensity correlation ...

The Peltier effect modulates the temperature of a junction comprising two different conductors in response to charge currents across the junction, which is used in solid-state heat pumps and temperature controllers in electronics. Recently, in spintronics, a spin counterpart of the Peltier effect was observed. The 'spin Peltier effect' modulates the temperature of a magnetic junction in respons...

The thermal ray theory is applied to the expérimental thermal scan on a razor blade. Good magnitude agreemettt is obtained using a far-field ray formula provided correction is made for the Boltzmann blackbody radiation law. The effect of conductivity variation with température is found to be small.

Scope NVTherm (Night Vision Thermal Imaging System Performance Model) is a PC based computer program which models parallel scan, serial scan, and staring thermal imagers that operate in the mid and far infrared spectral bands (3 to 12 micrometers wavelength). The model can only be used for thermal imagers which sense emitted, infrared light. NVTherm predicts the Minimum Resolvable Temperature D...

Proper evaluation of the surface and the depth of a burn wound, especially in the case of a severe burn, enables an appropriate choice of treatment to be made. This choice decides subsequently about the success of the entire medical treatment. Clinical assessment is currently the most frequently applied method in burn depth evaluation. Unfortunately the use of this method results in a high numb...

This paper examines an inverse problem which arises in thermal imaging. We investigate the problem of detecting and imaging corrosion in a material sample by applying a heat flux and measuring the induced temperature on the sample's exterior boundary. The goal is to identify the profile of some inaccessible portion of the boundary. We study the case in which one has data at every point on the b...

The development of a thermal imaging device which operates on the principle of differential evaporation (or condensation) of oil on a thin membrane is described. Section I,A summarizes the requirements of any thermal imaging method and develops the theory as applied to the particular case of the Evaporograph, emphasizing the consideration of scene temperatures near 20'C. It is shown that the gr...
