Shearography / ESPI Systems

The Shearog­ra­phy / ESPI Sys­tems are based on our SE sen­sors and isi-Stu­dio soft­ware in com­bi­na­tion with spe­cial acces­sories for dynam­ic, ther­mal and vac­u­um load­ing. They are usable for a vari­ety of appli­ca­tions, e.g. full field mea­sure­ment, non con­tact, non destruc­tive test­ing, vibra­tion, defor­ma­tion and strain measurement.

Software:

isi-Stu­dio is a spe­cial­ized soft­ware tool for auto­mat­ic and man­u­al con­trolled oper­at­ing and record­ing of (speck­le) interferometry.

SE-System Advantages

• Flex­i­ble and effi­cient: One sen­sor sys­tem for ther­mal, vac­u­um and dynam­ic loading
• Smart and mobile: Sen­sor oper­ates direct­ly by Lap­top (ful­ly dig­i­tal) — no addi­tion­al devices
• Ful­ly dig­i­tal sys­tem: First and only full dig­i­tal real­time phase­shift­ing shearog­ra­phy sensor
• No safe­ty require­ments: Laser class 1 with pow­er from 0,1W up to 12W per module
• High res­o­lu­tion and sen­si­tiv­i­ty: 5 MPix­el sen­sor, 10nm light phase reconstruction
• High qual­i­ty and vari­ety of lens­es: Designed for pro­fes­sion­al Nikon-F-mount lenses

 

Unique detection features

• Detec­tion of de-bond­ing to foam and hon­ey­comb where oth­er meth­ods fail
• Detec­tion also on back­side of sand­wich struc­ture by dynam­ic exci­ta­tion possible
• Auto­mat­ed detec­tion of image scale for deter­mi­na­tion of defect size

 

For rugged environments / in-service inspection

• High per­for­mance band pass fil­ter per­mits mea­sure­ment at day light (in house)
• Rapid and rigid mount­ing of sen­sor by flex­i­ble suc­tion cup tripod
• Ruggedi­zed sen­sor for rapid oper­a­tion with­out need for adjustment
• All in one flight case (sen­sor, vac­u­um tri­pod, dynamic/thermal excitation)
