Multi-Field-of-View Lidar Systems from Optech

An MFOV lidar records laser pulses backscattered from clouds at several receiver fields of view simultaneously.

This lidar is based on technology and algorithms developed and perfected by Canada's Defence Research Establishment Valcartier (DREV).  Optech delivered the first MFOV lidar system to DREV in 1989.

By probing clouds with an MFOV lidar and then applying DREV's algorithm, you can determine remotely the phase and liquid water content of clouds - large droplets, small droplets, ice and fog - and thus forecast more accurately the hazards they may pose to aviation, shipping and other interests.

By determining the backscattering, forward-scattering and extinction coefficient of clouds, an MFOV lidar provides accurate, real-time cloud forecasting without the errors that may be introduced by using atmospheric models.

Applications

  • Determine the contents of clouds dynamically and accurately
  • Characterize aircraft in-flight icing conditions
  • Military, naval and aviation applications

SIMPLE  -  Shipborne Infrared Maritime Parameter Lidar Equipment

Optech is currently developing a ship-mounted multi-field-of-view lidar system for DREV.  Our sub-contractor is INO, a well-known optics and photonics R&D company.

Applications

  • Continuously monitor atmospheric parameters relevant to the transmission of visible and infrared radiation
  • Complement atmospheric forecasting models.  Such models work well for open sea conditions but not in coastal areas, especially in bad weather.
  • Extrapolate results to other wavelengths of military interest

Features

  • Scans the whole sky:  Azimuth of 360°, elevation of 80°
  • Weatherproof:  Ruggedized for marine and bad-weather operation
  • Eight separate receiver FOVs and detector modules (gold modules at left in photograph above)
  • Eyesafe laser output
  • PC graphical user interface and data display
  • Motorized, remote-controlled scanner and telescope
