Facilities throughout the HPI are keenly interested in methods to record as-built plant design data. Laser scanning is one such technique; however, confusion about how these devices work is prevalent. So says an analysis from Spar Point Research (www.sparllc.com).
All laser scanning devices operate by first shining a focused laser light on the object being measured, then detecting and measuring the signal from light reflected by the object. In this sense, laser scanning is analogous to flash photography, taken one point at a time.
The two technologies most often used in terrestrial laser scanners are: 1) time-of-flight (TOF) devices and 2) phase-based devices (more correctly t
