What Does it Mean? Answers Behind More Acronyms
Friday, May 22, 2015

With over thousands of languages and billions of people in the world, there are bound to be a few words and acronyms that you don’t know off the top of your head. Though you may have finally just gotten the hang of “on fleek,” and knowing if someone’s “outfit game is strong” or not, continuing on from March, we have some more acronyms for you to learn. Relax; these won’t be popping up on social media sites any time soon. Rather, these are acronyms that you may have heard in a normal conversation before. These words may have a deeper meaning than you have initially thought.

· LIDAR
To those in the know, this is an acronym that can be as regularly used as radar. But to those who aren’t as educated in acronyms as we here at Greenlight Optics are, we’ll let you in on a secret: we didn’t make this word up. As you may have guessed from context clues, this acronym has the same suffix as radar. That’s because this acronym is actually a combination of the words “light” and “radar,” or, the popular meaning is “Light Detection and Ranging.” So just what is LIDAR? This is a remote sensing technology that, as you may have guessed, utilizes light — in the form of a pulsed laser — to measure variable distances to Earth. From the light pulses, scientists can gather data and information about the shape of the Earth and characteristics about its surface.

· Light-emitting diode
Better known as LEDs, these may be what light your home or office instead of incandescent bulbs. Lo and behold, we already answered the question for you; LED stands for Light-emitting diode. While there are numerous characteristics that set apart these lights from incandescent bulbs, this exact acronym refers to the semiconductor within the light source, which just so happens to be a diode. These diodes are now used in aviation, headlights, traffic signal lighting, camera flashes, video and television displays, and many other applications, and are available in a (bright) wide range of colors. But did you know the color of a light-emitting diode is determined is by the energy band gap of the semiconductor?

Whether you’re inquiring more about the Earth’s surface or are screwing in a new light-emitting diode into a desk lamp, you now are armed with more information to share with the billions of people on Earth. Plus, not only do you know the definitions of these terms, but you could even say your acronym game “is strong” because you’re now more knowledgeable with these terms.

Can’t get enough of acronyms? Tune in for the next installment on even more acronyms you may not have been aware of!
