The LIDAR can aim its laser beam in a wide range: its head rotates horizontally, a mirror flips vertically. The laser beam is used to measure the distance to the first object on its path. Laser rangefinders are used extensively in 3D object recognition , 3D object modelling, and a wide variety of computer vision -related fields.
The AN/PRC-6809 MBITR Clear is a variant of the MBITR, made available without encryption. While the PRC-148 includes US Type 1 capabilities in all versions, the PRC-6809 uses Level III Data Encryption Standard, making it available to police, firefighters, and militaries unable to obtain International Traffic in Arms Regulations (ITAR) approval.
