LIDAR stands for Light Detection and Ranging.
LIDAR is undoubtedly a tool we'll be seeing a lot more of in the future.Both RADAR and LIDAR bounce waves of electromagnetic radiation off objects to measure how far away it is from the light source. Where they differ is primarily in the wavelengths they occupy.By the Second World War
, radio frequency-based ranging technology was being used in military applications for detecting incoming enemy attacks. These low-frequency radio waves are ideal for traveling great distances through dense fog and cloud cover. Unfortunately, those long waves reduce the resolution of any objects being measured. At aruby laser
in the 1960s opened the way for higher frequency electromagnetic radiation sources to be used. Numerous pulses of laser light in the infrared, visible, or ultraviolet parts of the spectrum provide much tighter resolution at higher ranges, allowing LIDAR to reveal details a radar's wavelength would never see.
