Birçok düşük çözünürlüklü kayıt kullanarak kırınım desenlerinin çözünürlüğünün arttırılması

Holography attempts to record and reconstruct wave fields. The resolution limitationof the recording equipments causes some problems in the reconstructionprocess. An automatic method for the registration and stitching of low resolutiondiffraction patterns to form a higher resolution one is proposed. There is noprior knowledge about the 3D position of the object in the recordings and it is assumedthat there is only one particle in the object field. The method usesWignertransform, Canny edge detection and Hough transform to register the patterns,and some additional iterative methods depending on the local variance of thereconstructed patterns to stitch them. The performance of the overall systemis evaluated against object radius, noise in the original pattern, recording noiseand presence of multiple particles in the object field by computer simulations.
