1D phase-shift Electronic Speckle Pattern InterferometerTS-SI-1ZP

Instrument summarize

Electronic Speckle Pattern Interference is a new experiment mechanics method which had developed after holographic interferometry recently years ,it abandon the traditional screen printing photos complicated wet process and directly depend on the optical imaging system and the computer image collect disposal system to gain the interference fringes .This method had widely application in the project .,used to resolve the intensity and rigid problem during the project ,and also can used to measure the residual stressed.

TS-SI-1ZP one-dimensional electronic speckle pattern interferometer can real-time observe the electronic speckle pattern interferometry fringes which representative the off-plane displacement.

equip the stable three points curvature cantilever load device and the disc which is loaded by uniform load (air pressure) or concentration of the experimental apparatus. The entire system is stable and reliable, easy to adjust. and can get a better teaching results

Instrument innovation :

Can real-time observe the electronic speckle pattern interferometry fringes

Use one s single longitudinal mode semiconductor-pumped (green)solid laser as the light source ,making the stripes more clearly, more stable

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

The specially designed phase shifter makes the instruments function more perfect

The structure of the instrument reasonable ,smart ,beautiful .and have the good rigidity and convenience to adjustment

The optical components of the instrument have very designed and produced ,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
