3D Phase-shift electronic speckle pattern interferometer TS-SI-3P

Detailed Product Description

3D Phase-shift electronic speckle pattern interferometer TS-SI-3P

Instrument summarize

Phase-shift electronic speckle pattern interference technology (ESPI) is a new tentative mechanical method which had developed after photoelasticity and holographic interference (the method of photic measure mechanics ) It use laser interference and computer image disposal system to get the interferential stripe .This method had been widely use in project ,and also can use to settle the problem of  intensity and rigidity in the project , and also can used to measure the remnants stress

. 3D Phase-shift electronic speckle pattern interferometer can meet the need of measure object in-plane and of-plane displacement at the same time ,this instrument use the high-powered semiconductor laser as the light source ,and equip electronic speckle stripe real time display and Phase-shift disposal software .make the operate easy ,the measuring result have the better compatibility (easy to all-purpose the date disposal software connection )

Instrument characteristic

Can get the measuring object 3D displacement field , independently get the U,V,W field

use the single longitudinal mode semiconductor pump solid laser as the light source ,make the stripe more clearly, more stable

Use the high-resolution USB digital camera for image acquisition makes connections more reliable and processing more efficient

Use fiber laser spectrophotometer ,usage and  regulation is more convenient

special designed space Phase-shift and controller ,can get the 3D distributing chart of Phase-shift field

The instrument structure reasonable ,light ,beautiful and also has the characteristics of good rigidity and adjusting easy .

The optical components of the instrument have very design and produce ,for example the  beam expander is beyond hemispherical ,the spot of beam expander is big  and uniformity .The  holophote design according to the wavelength of the 530 nm laser .the reflectivity >99.9% .vacuum putamen coating , wear resistance and corrosion resistance
