Multispectral three-dimensional digital infrared thermal imaging

A multispectral three-dimensional (3-D) digital infrared thermal imaging (DITI) system is demonstrated for medical thermographic applications. In this system, temperature distribution and the three-dimensional geometrical surface profile are measured with different wavelengths and digitally stored in a computer separately. A texture-mapping technique is used for the accurate digital reconstruction of a 3-D temperature distribution of the human body. 3-D human body surface thermograms are obtained with this system.
