ESPI interferometer with radial sensibility

Submitted by jrpmichel on
speckle
strees intensity factor

hi all.

 

some time ago. i was measured the strees intesity factor (SIF) means electronic speckle pattern interferometry. i remeber used two equationes (in polar system) to compute by laest square method the KI and KII factors from measured displacement in the x and y directions. 

my question is: do you find some utility or advanage develop a interferometer with radial sensibility?, i appraise your opinion or any suggestion

thanks

hi jeorge

i do similar reasearch project like you,

but i hade to transmite x-y cordinate to radial cordinate , as u know ESPI are able to measure in one plane as whole in one test so we must acheave to x-displasement and y-displasement individualy and separately,

for more information and help me to find your exact problem, you  can cantanct me by navid.tajik [at] gmail.com (navid[dot]tajik[at]gmail[dot]com) too.

i hope i could help u.
