Field measuring instrument FlawHunter

surfacelaserfor the aerospace industry

The FlawHunter is an integrated NDT inspection device, equipped with an advanced, high-resolution Laser Shearography sensor with a vacuum (partial) excitation system. It is ergonomic & easy-to-use and is equipped with a workflow-oriented, GUI-display and left/right-hand button control. Regardless of the application, the FlawHunter provides reliable and resolute measurement results for in-field (service) NDT and quality control (post-production) operations. It can be used on any material & surface provided a stable vacuum can be generated within the vacuum seal (viewable inspection area). The FlawHunter has a fully-integrated control electronics, as such there are no external connections to PCs, electronics, vacuum pump/s, and/or hoses. The system only requires 1 connection to an external power source. It weighs 9 kgs (20 lbs) and can inspect 320 mm x 230 mm (12.6 ‘‘ x 9 ‘‘) within a maximum of 10 seconds* (including*; placement, clamping & measurement), yielding an inspection rate of 0.44 m²/min (4.7 ft²/min)! The vacuum pump typically requires 3-5 seconds to reach a steady vacuum level. The FlawHunter can be equipped with either; a 3.2 MPx (standard) / 5 Mpx (optional), 12-bit, GigE camera with a (respective) maximum frame rate of 37 / 24 Hz. The internal sensor has a fully SW–controllable, automatic shearing piezo. Using the 4+4 Phase Shifting technique in conjunction with stable vacuum control via the integrated vacuum pump & controller, users can set the vacuum (pressure) level down to -11 kPa with a tolerance of +/- 0.05 kPa. The result yields measurement images with the best definition and clarity with minimal noise.
