The system works using laser pulses from an aircraft to heat sections of atmosphere until a lensing effect is achieved. The lensing effect, caused by the refraction of light as it passes through the heated atmosphere, would allow spy aircraft to surveil enemies (whoever they may be...) "more effectively from long distances [in order] to collect vital information."

As Discover Magazine notes, the LDAL would work essentially like a lens made from glass, changing the density of the atmosphere to either focus the light coming from the ground, and hence the image, or scatter it in the case of anti-aircraft laser beams. BAE notes that in this sense, the system can behave as a "deflector shield," although it's probably fair to assume it wouldn't guard very well against photon torpedoes.

Unfortunately, it seems that BAE Systems doesn't think this technology will be battlefield-ready for another 50 years. But the kind of technology used in Star Trek takes time. At least this kind of time frame gives us plenty of room to develop a Federation on Earth, matter transporters, and androids that can think like humans but not use contractions.

What do you think about this atmospheric lensing system? Do you think investing in the LDAL would be a wise use of a government's funds? Let us know in the comments below!
