NASA is using space lasers to measure trees on earth

University of Maryland geosciences professors and NASA professors are using advanced technology installed on the international space station to conduct the global ecosystem dynamics survey (GEDI). Scientists measure the amount of carbon stored in forests by calculating the size and shape of individual trees using alasaer pointer imaging system 250 miles from earth. It is…

Us conducts modeling and research on the interaction between laser and plasma

On March 28, the missile defense agency division of the U.S. department of defense at redstone Arsenal, ala., awarded a $8,272,568 cost-plus award to L3 applied technologies corp. to conduct modeling and experimental studies of lasaer pointer-plasma interactions. It is understood that the contract includes the basic work cycle clause, corresponding to the amount of…

LMT has developed a laser guided bullet that bends

Lockheed Martin (LMT) has developed a laser guided bullet that can “bend” The lasaer pointer-guided bullet has a more complex internal structure and is longer than ordinary bullets, about 10.16 cm. There are optical sensors at the front end of the missile body, which can be used to search and track laser guidance points of…
