Purpose of the development: Small-sized holographic interferometer (IGI) is designed to measure the residual stresses in the nodes and details of metal structures.

Recommended application field: Modified CIC can be used for qualitative and quantitative analysis of deformation fields of the object surface when exposed to operating loads. CIC allows analysis of deformations in mechanical, thermal effects, when loaded by internal pressure to reveal hidden defects in the nodes of the composite materials and others.

Technical characteristic: While recording a hologram - 2. The number of write cycles - 1000. Interferogram processing time and the obtained values of deformation - 30. The maximum distance from the CIC to the object under study - 500 mm. The maximum size of the object - 240x80 mm. The minimum size of the object - 0.2x0.2 mm. Strain measurement accuracy - 0.03 microns. The diameter of the bore hole - 1 mm. The depth of the bore hole - 0.5mm. The accuracy of determining the residual voltage - 10% of the yield strength of the material.

Advantages over analogues: Originality CIC design is that, unlike the known test systems using holographic interferometry technique is not required to install the examined object in a measuring circuit, since the main unit is mounted on the surface of the CIC object. The latter allows to use CIC is not comfortable in the "field" conditions.

The development stage readiness: Pre-production model is made
