Laser Speckle Image Processing
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2016, Vol 7, Issue 5
Abstract
In this paper, Electronic laser speckle correlation technique has been adopted to measure small deformation of a specimen. A Low cost Opto-electronic Laser Speckle Interferometer is designed. Laser speckle images are captured ahead of the deformation stage and next in the deformation stage. Subtraction of these two digital speckle records, a fringe pattern called as Specklegram is obtained. This gives information about the deformation and results are verified by conventional gauge methods.
