Abstract

Typical construction and performance data for a pulsed time-of-flight laser rangefinding device intended for industrial measurements is presented. It is shown that by using a laser diode transmitter with a peak power of 5 - 15 W, a measurement range of a few tens of meters can be attained with respect to a noncooperative target. The available single shot resolution reaches mm-level in a fraction of a second. Accuracy depends greatly on the construction and adjustment of the device and levels of better than +/- 3 mm can be achieved in the above measurement range. Various construction details and other factors affecting to the available resolution and accuracy are discussed.
