It detects, analyzes, and locates directions of laser emissions [1] from laser guidance systems and laser rangefinders. Then it alerts the crew and can start various countermeasures, like smoke screen , aerosol screen (e.g. Shtora ), active laser self-defence weapon with laser dazzler (LSDW, used on the Chinese Type 99 main battle tank [ 2 ...
Technical support scams rely on social engineering to persuade victims that their device is infected with malware. [15] [16] Scammers use a variety of confidence tricks to persuade the victim to install remote desktop software, with which the scammer can then take control of the victim's computer.

Thermopile laser sensors find their use mainly where sensitivity to a wide spectral range is needed or where high laser powers need to be measured. Thermopile sensors are integrated into laser systems and laser sources and are used for sporadic as well as continuous monitoring of laser power, e.g. in feedback control loops.
Depending on the parameter of a light beam which is manipulated, modulators may be categorized into amplitude modulators, phase modulators, polarization modulators, etc. The easiest way to obtain modulation of intensity of a light beam is to modulate the current driving the light source, e.g. a laser diode .

Laser-induced fluorescence (LIF) or laser-stimulated fluorescence (LSF) [1] is a spectroscopic method in which an atom or molecule is excited to a higher energy level by the absorption of laser light followed by spontaneous emission of light. [2] [3] It was first reported by Zare and coworkers in 1968. [4] [5]
