6.2. Laser Scanning Standard
6.2.1. Laser Scanning Tilt
Scanning tilt is the vertical difference between the ends of a laser scan line.
• Up to 0.92° in a vertical direction from the scan origin (mirror motor mirror).
• Up to 2.46 mm when measured at 150 mm from the scan origin.
Measurement is done at the center of the laser scan line.
6.2.2.
Scanning Curvature
Scanning curvature is the maximum difference between the laser scan line and
the line between the ends of the laser scan line.
• Up to 1.17° in a vertical direction from the scan origin (mirror motor mirror).
• Up to 3.06 mm when measured at 150 mm from the scan origin.
Measurement is done from the center of the laser scan line.
