Software development

We have designed user -friendly software dedicated to optical measurements. The software can be associated with a specific man-machine interface when incorporated into the equipment.

F.A. - FringeAnalysis ®

F.A. - FringeAnalysis is specific software for the analysis and use of fringe images as used in holographic interferometry, speckle interferometry or structured light.
F.A. - FringeAnalysis has, for the last 10 years, already been the basic software underlying most of the applications developed by HOLO 3. It is also a standard processing tool used every day in our laboratories as part of our service. It benefits from our full experience in the field of optical measurement.

Application fields :

F.A. -FringeAnalysis is designed for use in a broad spectrum of applications requiring contactless optical analysis :

• Movement measurement
• Vibration analysis
  
• Non-destructive testing (NDT)
• Calculation of in-plane deformations and stresses
• 3D shape measurement
• Roughness measurement

The basic optical techniques turning around the F.A. - FringeAnalysis software are :

• Holographic interferometry
• Speckle interferometry (ESPI)
• Shearography
• Structured light (projection of fringes and Moiré patterns)

The main improvements that version 4 brings to the F.A. - FringeAnalysis software are the integration of the concept of the sensor and the time-related dimension.

Sensor concept :

The concept of a sensor is a way of grouping together and redering specialized the use of the software according to the type of detector associated with it (3D sensor, Holomap Sensor, Interferometry, etc...). A sensor is defined by a mechanical and optical configuration which is systematically associated with calibration. This approach simplifies the use of the software for non-specialists of optical applications, since an acquisition request to a sensor directly returns a measurement in the associated metric unit.

Time-related dimension :

F.A. - FringeAnalysis, starting from version 4, is capable managing of sequences measurements and therefore displaying the time-related development of a measurement . Introducing this possibility opens the way to a new approach of measurement exploitation. For instance, it measures a shape with the software displaying the deformation of a part in the form of a map or a profile. The current processing existing in the F.A. can be transposed to an entire sequence.
