THERMAL IMAGING GUIDEBOOK FOR BUILDING AND …

non-contact mode. Infrared thermometers for example. Infrared thermometers - thermal imaging cameras Infrared (IR) thermometers are reliable and very useful for single-spot temperature readings, but when scanning large areas, it’s easy to miss critical parts like air leakages, areas with insufficient insulation or water intrusion.

PRINCIPLES OF REMOTE SENSING

visible spectrum are designated as the infrared spectrum. British Astronomer William Herschel discovered this in 1800. The infrared region can be divided into two categories based on their radiation properties. Reflected IR (.7 µm - 3.0 µm) is used for remote sensing. Thermal IR (3 µm - …

INTERPRETATION OF INFRARED SPECTRA, A PRACTICAL …

2 INFRARED SPECTROSCOPY mind is that a successful interpretation is based not only on the presence of particular bands within the spectrum, but also the absence of other important bands. Complete classes of compounds can be rapidly excluded during the interpretation by the use of no-band information. It must be understood that this article addresses

The Fundamentals of Infrared Spectroscopy

Fundamentals of Infrared Spectroscopy Midac Corporation 2 some cases this involves breaking the light up into component wavelengths so that the sample is exposed to only a narrow region of the spectrum at any one time. In this form of infrared spectroscopy the wavelength of light incident on the detector at a given time is known.

INFRARED SPECTROSCOPY (IR)

AN IR SPECTRUM IN ABSORPTION MODE The IR spectrum is basically a plot of transmitted (or absorbed) frequencies vs. intensity of the transmission (or absorption). Frequencies appear in the x-axis in units of inverse centimeters (wavenumbers), and intensities are plotted on the y-axis in percentage units.
