Shearography / ESPI Systems

SE2 neu array


The Shearography / ESPI Systems are based on our SE sensors and isi-Studio software in combination with special accessories for dynamic, thermal and vacuum loading. They are usable for a variety of applications, e.g. full field measurement, non contact, non destructive testing, vibration, deformation and strain measurement.

SE-System Advantages

  • Flexible and efficient: One sensor system for thermal, vacuum and dynamic loading
  • Smart and mobile: Sensor operates directly by Laptop (fully digital) – no additional devices
  • Fully digital system: First and only full digital realtime phaseshifting shearography sensor
  • No safety requirements: Laser class 1 with power from 0,1W up to 12W per module
  • High resolution and sensitivity: 5 MPixel sensor, 10nm light phase reconstruction
  • High quality and variety of lenses: Designed for professional Nikon-F-mount lenses


Unique detection features

  • Detection of de-bonding to foam and honeycomb where other methods fail
  • Detection also on backside of sandwich structure by dynamic excitation possible
  • Automated detection of image scale for determination of defect size


For rugged environments / in-service inspection

  • High performance band pass filter permits measurement at day light (in house)
  • Rapid and rigid mounting of sensor by flexible suction cup tripod
  • Ruggedized sensor for rapid operation without need for adjustment
  • All in one flight case (sensor, vacuum tripod, dynamic/thermal excitation)



Application example for ESPI / Shearography:

Dynamic loading on rudder blade

Dynamic loading on a yacht mast

Dynamic excitation on a spacecraft

Dynamic loading on a wind turbine blade and resin bridges

Dynamic loading on a large yacht hull

NDT on wind rotor blades

Vacuum loading on battery packs
