API is a world leader in coordinate measurement solutions. API provides laser trackers, CMM arms, non-contact laser scanners, and machine tool health and calibration equipment. Our products and services are used by many of the world’s leading automotive, aerospace, shipyard, and machine tool manufacturers worldwide.



9D LADAR is the fastest, most accurate interferometry-based non-contact measurement system in the world. 9D LADAR provides micron-level resolution while eliminating issues associated with surface reflectivity, slow data acquisition, restrictive incident angles, and susceptibility to the production environment.

Problem Statement:

  • Slow scanning speed
  • Low accuracy and short range
  • Limited incident angle
  • Restrictive surface reflectivity and use of sprays

Technology Solution Statement:

API’s 9D LADAR uses patented optical frequency chirping interferometry technology to generate a wide spectrum for optical interference. This technology allows for fast scanning speed with high accuracy at a long distance regardless of surface reflectivity or incidence angle.

Benefits Statement:

  • Up to 25 meters of range
  • 25 micron + 6 micron per meter 3D accuracy
  • Up to 85 degrees incidence angle
  • 20,000 points per second
  • Non-contact measurement
