Portable laser shear speckle detection systemFlawHunter

FlawHunter is an integrated non-destructive testing device equipped with advanced high-resolution laser shear imaging sensors and vacuum partial excitation systems. It is ergonomic and easy to use, equipped with a workflow oriented GUI display and left/right button control. Regardless of the application, FlawHuntER can provide reliable and dependable measurement results for on-site non-destructive testing and quality control (post production) services. It can be used on any material and surface as long as a stable vacuum is generated within the vacuum seal (visible inspection area).

FlawHunter features integrated control electronics, eliminating the need for external connections to PCs, electronic components, vacuum pumps, and/or hoses. The system only requires one external power connection. It weighs 9kg（20Ib）Can check 320 mm x 230mm (12.6 'x) within a maximum of 10 seconds 9 ') (including placement, clamping, and measurement), inspection rate: 0.44 square meters per minute (4.7ft ²/min), vacuum pump usually takes 3-5 seconds to reach a stable vacuum degree.

FlawHunter system composition:

1. Hardware:

1) Laser light sources (such as semiconductor lasers, typically with a wavelength of)532nm or 635nm)Shear interferometer (including optical components such as spectrometers and reflectors).

2) It can be equipped with any one, a 3.2MPx (standard)/5Mpx (optional) 12 bit GigE camera, with a maximum frame rate of 37/24Hz. The internal sensors have SW controllable automatic cutting piezoelectric ceramics. By combining the 4+4 phase shift technique with stable vacuum control achieved through integrated vacuum pumps and controllers, users can set the vacuum (pressure) level to -11kPa with a tolerance of ± 0.05kPa, resulting in measurement images with optimal clarity and minimal noise.

3) Incentive devices (such as hot air guns, vacuum hoods, mechanical vibrators, etc.).
