A sailor checking the temperature of a ventilation system. Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an electromagnetic field, as in induction heating; where the object is contained in a vacuum or another controlled atmosphere; or in applications where a fast response is required, the accurate surface temperature is desired or ...

COVID-19 rapid testing in Rwanda. An antigen is the part of a pathogen that elicits an immune response. Antigen tests look for antigen proteins from the viral surface.
Individual soldiers carry small laser sensors scattered over their bodies, which detect when the soldier has been illuminated by a firearm's laser. Each laser transmitter is set to mimic the effective range of the weapon on which it is used. When a person is "hit", a medic can use the digital readout to determine which first aid method to practice.
Due to their compact design, beam splitters of this type are particularly easy to install in infrared detectors. [9] At this application, the radiation enters through the aperture opening of the detector and is split into several beams of equal intensity but different directions by internal highly reflective microstructures. Each beam hits a ...
A laser warning receiver is a warning system used as a passive military defence. It detects, analyzes, and locates directions of laser emissions [ 1 ] from laser guidance systems and laser rangefinders .

The word laser originated as an acronym for light amplification by stimulated emission of radiation. [1] [2] The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow and the optical amplifier patented by Gordon Gould. [3] [4] [5]
