The Vector-DD is a direct detection
(DD) 3D (range, angle, angle) active imager with an all-sky full
hemisphere scanner. It employs a nodal point design so that all the
lines-of-sight converge to a single point at the instrument*.
In addition, two wavelengths can be transmitted so that differential
reflectivity information can be derived. The unit is compact and
portable and operates from 24V DC.
* Angle and range resolutions are of
the order 0.5mrad and 15cm respectively.
