Products and technologies

Several optical technologies are proposed to measure surface deformation : speckle interferometry offers measurement precision of within 0.1 micrometer and CORRELI 3D, a white light imagery technique is an easy way of getting to 3D displacement mapping.  

Holo3 offers vibration measurement processes based on laser techniques : the laser vibrometer dispenses with the need for any instrumentation like accelerometer bonding, wiring, etc... Speckle interferometry techniques supply full-field information, which is particularly effective for modal analysis and as an investigation tool in the case of complex vibration behavior.  

The development of digital cameras (in terms of rates and spatial resolution) and the progress made with optical phase calculation logarithms have resulted in 3D imagery techniques. Thanks to stringent calibration processes, a camera is able to become a real dimensional metrology tool.  

The parts are tested by the application of a mechanical, pneumatic or thermal stress.  

Monitoring of displacements with Visio-Track is based on the monotoring of one or several points by a tracking camera. When the system is calibrated, we obtain the movement of a point in space as a function of time.  

LIBS : Laser Induced Breakdown Spectroscopy (Libs) ou Laser Induced Plasma Spectroscopy (Lips) is a way of analysing components (atoms/molecules)of solid or powder materials, but also of gases of liquids and even aerosols.  

In conventional color imagery, 3 different images are obtained corresponding to red, green and blue, whereas with multi-spectral imagery, far more images are acquired, each corresponding to very narrow band of the spectrum.  

The forming of an image in a camera is based above all on a fundamental optical characteristic of the surfaces their bi-direction reflectance.
