hi all.
年代ome 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 thexandydirections.
my question is: do you find some utility or advanage develop a interferometer with radial sensibility?, i appraise your opinion or any suggestion
thanks
