Near Infrared Thermography with Silicon FPA - Comparison to MWIR and LWIR Thermography
An ideal thermographic camera could be defined as an uncooled system with high spatial and thermal resolutions featuring a video frame rate, and a short calibration process. In this paper a measurement system based on Silicon Focal Plane Array (FPA) operating in the Near Infrared spectral band (0.7 − 1.1μm) is proposed. This system offers an excellent spatial resolution, a low cost and compactn...
متن کاملDouble Pulse Infrared Thermography
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 ...
متن کاملInfrared Thermography in Pain Medicine
Since BC 400 when Hippocrates used temperature in a diagnosis by applying mud to a patient's body and speculating that dry areas had disease, temperature has been an important area of interest in medicine. The skin is a very important organ in temperature regulation, and body temperature is controlled by the combined control of the central and autonomic nerve system. Infrared thermography (IRT)...
متن کاملInfrared Thermography in Sports Activity
The origin of infrared thermography comes in 1800 when William Herschel discovered thermal radiation, the invisible light later called infrared, but only in the mid-sixties infrared thermography became a technique of temperature cartography. He proved that this radiation, called infrared, followed the same law as visible light. Later, this phenomenon was connected with the laws of Planck and St...
متن کامل- 1 - Pulse Phase Infrared Thermography
In this paper a novel approach is proposed which combines simultaneously advantages both of pulse (PT) and modulated (MT) infrared thermography. In a nondestructive evaluation perspective, the specimen is pulse-heated as in PT and the mix of frequencies of the thermal waves launched into the specimen are unscrambled by performing the Fourier transform of the temperature evolution over the field...
