Neptec offers viable solutions for degraded visual environment mapping in brownout, whiteout and fogout conditions.

With systems for both land and aerial-based vehicles, on both manned and unmanned platforms, Neptec solutions can significantly aid surveillance systems.
Neptec's Degraded Visual Environment Mapping technologies work by using a LiDAR system to penetrate through whiteout, fogout and brownout conditions. Using a proprietary detection method, Neptec systems outline objects within an obscurant cloud.
This system can be used on a variety of manned and unmanned land and aerial vehicles. Capable of measuring a terrain's slope and plotting out a detailed geography of the landscape, this system can also detect wires during forward flight.
Neptec's Obscurant Penetrating Autosynchronous LiDAR (OPAL) uses a proprietary optical design that minimizes the detector saturation caused by the back-scattering of light by nearby particles suspended in air. OPAL also exploits the full extent of the returned light signals to extract targets and obstacles engulfed in obscurants. OPAL has been tested at several facilities.
