 • Built-in self diagnostics and testing
 
 
 
 
 
 
OSi’s Optical Wind and Visibility sensor (OWV) is a breakthrough in measuring clear air turbulence, large body air / wind movement and atmospheric visibility over a long path (50 to 200 meters) – all in a single, low cost sensor. The sensor operates on a combination of long path optical extinction and optical scintillation. All the electronics are housed in the OWV with a folded path being established by placing a corner cube reflector down-range at the desired distance.

OWV can also be configured for use at airports as a wake vortex detection system. This has been extensively field tested in this application as part of NASA’s Airspace Systems Program.This makes the OWV an incredibly versatile sensor that can be applied to many different applications in environments as diverse as airports, petrochemical plants (for fence-line monitoring) and across rivers and inlets.
