posted about using SDI-derived raster laser technology to detect and slay
mosquitos. Looks like a group of Royal Smart Persons figured out a way to
do it:</FONT></FONT></SPAN></DIV>

the topic of using lasers to zap mosquitoes in the late 80s, about 6 years
before I began lurking on ExI-chat. Turns out there is a directed energy
weapon aiming technique that uses a two axis fast steering mirror to create a
lissajous pattern in a given area.</FONT></SPAN></DIV>

incoming missiles with a directed energy beam, or with particle beam
weapons. We may see such a thing in action soon if the Iranians decide to
fire missiles at Israel. Let us fondly hope not.</FONT></SPAN></DIV>

pattern on a given area in the sky and examines the return signal. From
this it determines what is the object in the sky, and if it is an incoming
missile (or in another application a mosquito) it sends a mighty flash of light
at the object.</FONT></SPAN></DIV>

the start of a nice tan, but even the chalkiest doughboys among us would be
unlikely to get a sunburn in ten minutes. Yet if you received that same
dose of solar flux in one tenth of a second, you would be unlikely to
survive, for it would ruin your skin and raise your body temperature
quickly. Likewise, the amount of energy in a typical camera flash is
plenty to slay a mosquito if we manage to get it all on her simultaneously to
raise her body temperature 30C. The article above doesn't say, but I can
imagine using SDI tech to identify and shoot down individual
mosquitoes.</FONT></SPAN></DIV>
