First Demonstration of DASER Light Suppression Device

Wednesday, April 1, 2015

Researcher in Southern California announced the first demonstration of the DASER light suppression device. DASER stands for Dark Attenuation and Suppression of Environmental Radiation and works using the principles of wide-field incoherent destructive interference. Energy conservation is achieved by an emitter in the back of the device causing some researchers to describe it as a vacuum cleaner for photons. Operating over the visible spectrum, the DASER can extinguish light over an area as large 50 centimeters in diameter (about 20 inches); work is being done to extend the area. Multiple DASERs can also be used in parallel as long as field overlap is avoided. The military is interested in the device as a way to conduct night combat operations during the day and law enforcement considers it as a practical way to suppress building light in field operations. Who knows, the DASER might even allow sports fans to enjoy night games during the day... Happy April First!
