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]), laser jammer, etc. Detectors used in LWR are usually based on a semiconductor photodetector array, which is typically ...
A laser jammer or lidar jammer is an electronic device used by drivers to prevent users of a LIDAR (or laser) gun from obtaining speed readings of their vehicle. Laser jammers are not to be confused with radar jammers. To jam LIDAR, laser jammers first must detect the emitted light, normally infrared light on the 904 nm wavelength. [12]
A laser designator is a laser light source which is used to designate a target. Laser designators provide targeting for laser-guided bombs , missiles , or precision artillery munitions, such as the Paveway series of bombs, AGM-114 Hellfire , or the M712 Copperhead round, respectively.
Radar detectors fine up to 3 points from the driving license and €200. [27] Ka narrow, laser, Autovelox Switzerland: Detectors and jammers are illegal to own, use or sell. [10] 660SFr fine. Radar detectors will be confiscated and destroyed. The use of any GPS-based device to locate speed cameras is also illegal.
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.
Two colour detectors are used in some systems to assist in the suppression of background clutter and lower FAR. Even though it solves some problems, it creates others as it complicates the system further due to the optical, sensitivity and extremely high pixel rate requirements which impact negatively on cost and reliability.

Some motorists install radar detectors which can alert them to the presence of a speed trap ahead, and the microwave signals from radar may also change the quality of reception of AM and FM radio signals when tuned to a weak station. For these reasons, hand-held radar typically includes an on-off trigger and the radar is only turned on when the ...
