Description

Teledyne Optech Inc. has been making laser systems for over 40 years for space, airborne and fixed applications.  Participating with the US Navy, Army Corps of Engineers and NOAA, Teledyne Optech developed the first airborne green laser scanning system, SHOALS (Scanning Hydrographic Oceanographic Airborne Laser System).  Continuing the Army / Navy /NOAA partnership, the survey consortium JALBTCX (Joint Airborne Lidar Bathymetric Technical Center of Expertise) was born.  The next development was the Coastal Zone Mapping Imaging Lidar (CZMIL) system, which first flew in 2012; there are now 9 systems worldwide.  Improvements in the CZMIL system electronics and processing produced the Nova system.  Now, in 2021, the CZMIL Supernova is introduced.  This system has the deepest depth penetration on the market, yet can be programmed for shallow water survey where water can be optically complex and higher point densities can be required.  Key products points:

  • Programmable for deep, shallow and topographic modes
  • Best depth penetration on the market:  4.4 /Kd for deep channel and 2.9/Kd for shallow channel
  • SmartSpacing mode for more even point distribution across the swath
  • Onboard realtime data processing - land the survey flight with a point cloud
  • CARIS Base Editor software for data processing, visualization and product generation
  • CARIS Bathy Database for data management and exploitation
