US Patent 11629958 Increment measuring device and process

A process for determining and indicating an incremental point on a target surface comprises independently rotating a first laser to project a first laser point on the target surface; independently rotating a second laser to project a second laser point on the target surface; measuring an angle of rotation for each of the first laser and the second laser; and based on the measured angle of rotation for each of the first laser and the second laser, calculating a target angle of rotation corresponding to an incremental point between the first laser point and the second laser point on the target surface. A third laser is independently rotated until it reaches the target angle of rotation and projects a third laser point at the incremental point on the target surface.
