75 FoV of 100o,” said My-Linh Truong. “It’s also constructed for NFB [nadir/ forward/backward] scanning. With traditional airborne Lidar, most people understand the nadir orientation of points you get on the ground, but with NFB you get additional points and shots 10o ahead and 10o behind the UAV, which allows more detailed and higher quality 3D modelling of structures like transmission towers, power poles and building facades, as well as complex terrain across flight paths. “And if an end-user has a flight path with overlaps in each pass, NFB really helps guarantee that they’re capturing complete and fine detail on the assets they’re looking to model.” Operating at a maximum of 2.4 MHz PRR, the VUX-160²³ has a measuring range of up to 720 m and can measure up to five targets per pulse, although if the PRR is configured downwards, to the minimum of 300 kHz, these increase to up to 1800 m and 32 targets respectively. Its scanner functions using a rotating polygon mirror, with a scan speed of up to 400 lines/second and an angle measurement resolution of 0.001o. “The VUX-160²³ also has five camera ports, so customers with large UAVs or crewed aircraft can integrate up to five cameras, potentially in nadir or oblique angles for added visual detail to overlay on the Lidar model,” Truong added. “We can also integrate either Applanix’s AP+30 or +50 GNSS-IMU inside the housing, for additional accurate information on roll, pitch, heading and position in a compact package, with the total system weight coming up to 3.15 kg if the end-user goes for those. This configuration is ideal for high-performance VTOL UAV platforms.” An Ethernet connection of 10, 100 or 1 Gbit/s is suitable for interfacing with the system for scanning data outputs and configuration. The system is powered via an 18-34 V DC input and consumes 60 W in normal operations, with a typical weight of 2.65 kg; its enclosure measures 283 x 134 x 117 mm. The company also talked about its VUX-120²³, which has a maximum range of up to 400 m and up to five targets per pulse when set for a 2.4 GHz PRR. The scan parameters are the same as on the VUX-160²³, although the system consumes just 45 W in standard operation and weighs roughly 2.3 kg – 3 kg if the end-user chooses the optional integration of an Applanix APX-20 UAV GNSS-IMU, or 3.6 kg if either of the more powerful AP+30 or +50 units are selected. Up to two cameras can be integrated, as well as dual Ethernet interfaces if needed.
