Abstract
Improved versatility, reliability and performance for field-deployable spatial positioning or measurement systems that use rotating laser fans or beams. Teachings include [1] A system integrated field-deployable length standard uses a reelable tape with positional indents; [2] the use of labyrinth seals at interface volumes between rotating laser heads and transmitter assemblies to prevent ingress of contaminants and allow for elimination of the use of rotary seals; [3] new dynamic leveling techniques to plumb positional laser transmitter systems; [4] strobe beam configurations for improved near/far performance; and [5] a vertical mode sensing scheme that allows switching to measuring tall structures when needed.
