  • Acronym for "LIght Detection And Ranging." Whenever I see this word I can't help but think about Napoleon Dynamite's liger.

  • most of the examples are in lowercase, but a search on google scholar for 'light detection and ranging' indicates that it is most often used in all capitals, less frequently as all lower case, and perhaps most accurately as 'LiDAR'. Does anyone know when an acronymn becomes sufficiently colloquial to be used in all lowercase, and if LiDAR has met this?
