Shearwin features |
| Automatic project and workflow management: Each operation step of your measurement or image operation is recorded and can be repeated with recall and redo functions or manipulated parameters. | ![]() |
| Exposure of speckle interferograms in different acquisition techniques. This is for example the 3x3 or 4x4 phase step techniques, as well as the real time and the time average technique with renewed reference frame. | |
| Automatic measuring routines for in-plane and out-of-plane holography as well as in-plane and out-of plane shearography. In combination with the isi-strainograph or/and the isi-sys laserdiode units or liquid crystal shutters there is the option to extend the hardware to autmated 3D deformation and strain analysis system. | |

ShearwinNT offers various standard Filter-types and special filters adapted to discontinuities of phase maps using sin/cos-transformation. |
| A new feature of ShearwinNT is the Fast Fourier Transformation (FFT) of interferograms including FFT Filtering and FFT evaluation of the interference phase. An outstanding function of ShearwinNT is the automatic sign correction after FFT phase evaluation. | ![]() |
|
|
There is a easy handling tool for masking your images by circles rectangles and polygons as well as inverting these functions to cut parts of the image, which contain any irregularities and the parts of interest. |
| Shearwin contains standard demodulation or unwrapping algorithm, that removes the phase steps and converts the filtered phase map into a continuous plot. | ![]() |
| If your phase map is filtered and demodulated there is the choice of automatic evaluation by the parameters such like the wave length of the used light source that have been saved in the image property sheets during the measurements. |

For presentation or analysis of your results ShearwinNT offers tools such as 2D or 3D plots. |
| If you want to include your results into other documents, you have the choice of common in and output image formats (bmp, tiff, jpg, …) as well as the compatibility for numerical exchanges to Math-Lab or Exel and other software | |
|
ShearwinNT is independent of the pixel format of the CCD camera, so you can extend your camera hardware to XXXX x YYYY pixels. |
|
| You have the choice of several image operation with ShearwinNT such as basic mathematical and logical image operations (+,-,*,/ …) | |
|
The software includs a self calibration function for the piezo-drive that adapts automatically to the phase shift steps to your Laser wave length. |
|
|
Automatic shearing adjustment: Automatic shearing adjustment and control with the isi-sys shearcontrol unit with or without DMS feedback controlled piezomechanical stablisation in the nm range. This can be also applied to stabilisation of position sensitive arrangements. |
