speckle pattern interferometry/stress measurment method

navidtajik's picture

I’m working on optical method for displacement measurement. and this is interesting to know more about application and development of these methods like ESPI , SHEAROGRAPHY anf HOLOGRAPHY . for example i face with a company that climb their product can give displacement and so strain field in many material and many geometry even in 3-D shapes!!

So there is a basically question: is it possible use of these methods as a practical method in industrial or as portable and conventional tools like strain gauge method?

Is there any other (except new optical method like holography and interferometry) experimental method for finding stress and strain field ?

i am developing a portable system to measure strain field and displacement fieds. this system works with the Digital Image Correlation technique. its very easy. you only need frames of a recordered video.

hello Jorge

tank for consideration

could you tell meis it availabe or must be design and made by researcher?

if this accossories is made before by companies, could you give me the adress?
