Description

The SA Photonics SafeLanding system offers a means for carrying out falling weight deflectometry measurement much more quickly than is possible with conventional equipment. With high-rate calibrated impact stimulation and all-optical sensing, SafeLanding collects high-quality deflectometry data while the unit is in motion. Unlike rolling wheel deflectometers, SafeLanding does not rely on heavy weights to produce a measurable deflection basin. Rather, the complete unit can be towed by an ordinary pickup truck or SUV. Measurements are recorded automatically as the unit is towed, without operator intervention. Immediate analysis tells the operator the system measurement state, eliminating failed data runs. All data are collected with GPS date and location stamps to ensure unambiguous results. With each pass, SafeLanding records data on 100 points across the line of travel to a total width up to 1.7 meters, and at a density of one sample row every 0.7 meters along the line of travel. Higher density data acquisition is supported by towing more slowly.
