505 0  Walsh Functions, Walsh Filters and Self-Similarity -- 
       Transverse Intensity Distribution on the Far-field Plane 
       of azimuthal Walsh Filters -- Self-Similarity in 
       transverse intensity distributions on the Far-Field plane 
       of Self-Similar azimuthal Walsh filters -- Transverse 
       Intensity Distribution in the Far-field region of 
       azimuthal Walsh Filters -- Self-similarity in transverse 
       intensity distributions in the far-field region of self-
       similar azimuthal Walsh filters -- Future Prospects 
520    This book explores the possibility of using azimuthal 
       Walsh filters as an effective tool for manipulating far-
       field diffraction characteristics near the focal plane of 
       rotationally symmetric imaging systems. It discusses the 
       generation and synthesis of azimuthal Walsh filters, and 
       explores the inherent self-similarity presented in various
       orders of these filters, classifying them into self-
       similar groups and sub-groups. Further, it demonstrates 
       that azimuthal Walsh filters possess a unique rotational 
       self-similarity exhibited among adjacent orders. Serving 
       as an atlas of diffraction phenomena with pupil functions 
       represented by azimuthal Walsh filters of different orders,
       this book describes how orthogonality and self-similarity 
       of these filters could be harnessed to sculpture 2D and 3D
       light distributions near the focus
