7.2. Laser Scanning Specification
7.2.1.
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 3.1 mm at 150 mm from the scan origin.
7.2.2. 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 3.3 mm at 150 mm from the scan origin.
