Laser radar or ladar is a bit unclear in its definition. For us it is a system making 3D images of a volume. The volume scanned is splitted up in volume pixels (voxels) where all voxels have a coordinate related to the system itself. If the complete system have special sensors to know where it is all voxels can be defined to a global coordinate. Here we mix technologies and more focus to what sensor can fulfill specific demands of a known application. We have one page for each main method of ladar with more information.Pls click the link.
  • Time of flight laser radar scanners. This is a time of flight distance meter that is scanned over an area. Distance and angle gives the position of the vowel. This is what many call a traditional laser radar system or Ladar if preferred. This system can also have a phase sensing distance meter. Ranges are meters to km in range and accuracy from some mm to about 1 meter for longer ranges.
  • Matrix based ladar systems. Here we have no moving parts and a laser emitting a short pulse. There is a matrix based camera than receive the reflex of the laser beam and by time of flight calculations of each pixel we have a coordinate for the vowel. Ranges differs from 10m meter to 10 Km. Short range systems can do 1 mm to 10 cm in accuracy.
  • Triangulation based scanners use a laser with line optics that is scanned over an area. The camera is positioned in an angle and by triangulation we can see the reflex location in 3D and the 3D vowel position
  • Correlation 3D scanners using cameras and a unique software to get 3D from camera images.
Application areas and designs of systems

We have several special versions for different application areas. When possible we use same parts inside but the solution can look very different. Special areas of designs are.

  • Airborne scanners for different platforms. Here we have small units for unmanned UAV systems to larger systems for aircraft's higher altitude.
  • Sub sea laser radar systems for 3D sub sea bottom mapping. We have also a sub sea 3D coordinate measuring solution with very high accuracy .
  • Car and robot based scanners than can scan the surrounding areas when GIS and reverse engineering applications is one area.
  • Industrial scanners and sensors. These can cower most areas in industry from hot steel mills to levels in silos
  • Security scanners for home land security. As we can measure in 3D we can see many things that normal cameras will miss.
  • FOD debris detection scanner than can operate as a change detectiun device. This system is very high resolution and can see the smallest changes in 3D shape on an area. One other application is bomb detection at long ranges. We hhhhhave detected burried bombs at 100 meter distance at tests in Sweden
