LiDAR

[LIGH-dar] /ˈlʌɪdɑː/

LiDAR, an acronym for Light Detection and Ranging, is a technique for creating depth maps of objects and environments. LiDAR works by reflecting light from a laser off the target object and measuring the amount of time before the light returns to the receiver. These return times can then be processed and compiled into an overall map of the target object or environment. The technique can be used to create distance maps of landscapes or combined with 3D scanning to create digital models of 3D objects. At SLV LAB, LiDAR was used in the Mouthful of Dust projects to replicate the exact scale of Ned Kelly's armour for the digital versions.
