Infrared coatings

Applied Optics, 1988
IR Coatings are optical interference coatings used for at least one of the atmospheric windows from 3-5 or from 8-12 microns. Particulary interesting are coatings which are additionally used for the visible spectrum, or high power coatings for the CO2-laser at 10.6 microns. The main applications of IRCs are thermal imagers and laser systems.

Infrared Thermography

2018
Historically, brown adipose tissue has been elusive and not easy to detect, hence its relative obscurity in human physiology until its rediscovery in 2009. At that point, it was proven that the symmetrical artefacts frequently detected on positron emission tomography-computed tomography (PET-CT), which resolved if the environment was kept warm, were ...

Infrared immunoassay

Clinical Biochemistry, 1989
An immunoassay method based on the labelling of an antigen with a transition-metal carbonyl organometallic marker and detection of the label by Fourier transform infrared (FT-IR) spectroscopy is described. The viability of this novel non-isotopic approach, termed infrared immunoassay (IRIA), has been evaluated in the quantitative determination of the ...

Infrared spectrometry

Applied Optics, 1982
A brief history of the early work on Fourier spectroscopy at the Johns Hopkins University is given as well as a general description of the techniques of Fourier and Hadamard transform spectroscopy. The techniques of tunable diode laser spectroscopy and the difference frequency technique for IR spectral studies are also briefly described including some ...

Infrared photoretinoscope

Applied Optics, 1987
A modification of the technique of photoretinoscopy is presented which allows measurement of the refractive state of the eye in noncooperative subjects and in very small eyes. Infrared light provided by high-output infrared LEDs permits measurement at large pupil sizes and thereby better resolution.
