5-2. Laser Scanning Standards
5-2-1. Laser Scanning Tilt
Laser scanning tilt is the vertical difference between both ends of a laser scan line. Measure
it in the middle of the laser scan line.
▪ Up to 1.2 degrees angle in vertical direction from the scan origin (mirror motor).
▪ Up to 3.1mm at 150mm from the scan origin. (Measured at
0 degree of Skew Angle.)
5-2-2. Scanning Curvature
The maximum difference between the laser scan line and the line between both ends of the
laser scan line. Measure it in the middle of the laser scan line.
▪ Up to 1.27 degrees angle in vertical direction from the scan origin (mirror motor).
▪ Up to 3.3mm at 150mm from the scan origin.
