Paper Abstract

The quantification of the deformations presented by mechanical parts is a useful tool for several applications in engineering; regularly this quantification is performed a posteriori. In this work, a digital holographic interferometer for measuring micro-deformation at video rate is presented. The interferometer is developed with the use of the parallel paradigm of CUDA™ (Compute Unified Device Architecture). A commercial Graphics Processor Unit (GPU) is used to accelerate phase processing from the recorded holograms. The proposed method can process record holograms of 1024x1024 pixels in 48 milliseconds. At the best performance of the method, it processes 21 frames per second (FPS). This benchmark surpasses 133-times the best performance of the method on a regular CPU.
