How Fast is Laser Scanning?
Much like a 35mm camera, the laser has exposure settings that need to be adjusted depending upon the nature of the object being scanned. In general, dark-colored objects require longer exposure settings than light-colored objects and longer exposure settings require the system to operate at slower velocities if data integrity is to be maintained. The point sampling distance requested by the user also affects scanning speeds. In general, we have experienced “real world” scanning speeds of 30,000 to 40,000 points per second although some situations may require slower scanning speeds and other situations may permit scanning at full scan rate of the probe which is 225,000 points per second. In all cases, laser scanning tends to be much faster than a CMM and somewhat faster than mechanical tracing systems.
