2D Digital Speckle correlation Measurement System- DSC-1000

Instrument summarize

2D digital speckle correlation measurement system can be used for 2D surface in-plane deformation measurement, especially in large deformation measurements. The system can be equipped with ordinary zoom lens and microscope lens thus, the system can meet the macro and micro-2D in-plane displacement measurement needs. With the powerful 2D digital speckle processing software, makes the system can measure the whole field deformation measuring of large-scale structure or material on the surface. and get the strain distribution . According to the principle of stereoscopic vision, with two 2D measurement system and equip  a 3D deformation measuring software and 3Dmeasurement calibration system can constitute a set surface deformation measurement system.
