Paramasivam Senthilkumaran is currently working as a professor in the Physics Department at the Indian Institute of Technology Delhi. He is also heading Optics and Photonics Centre at Indian Institute of Technology Delhi. He was a senior project officer and received his PhD from the Indian Institute of Technology Madras in 1995. He was a recipient of the Young Scientist Award from the Indian National Science Academy, New Delhi, and Alexander von Humboldt fellowship, Germany, in 1997 and 2001 respectively. Senthilkumaran has been teaching undergraduate and postgraduate courses on a variety of subjects including basic physics, electromagnetic theory, optics and lasers, Fourier optics and holography. His research interests include optical beam shaping, optical phase singularities, Berry and Pancharatnam topological phases, fiber optics, holography, non-destructive testing techniques, shear interferometry, Talbot interferometry, speckle metrology and non-linear optics. He has authored/coauthored more than 150 research publications, has more than 15 years of experience researching singularities in optics, and has supervised sixteen doctoral theses.
This book aims to introduce the rapidly expanding field of singular optics, notably phase and polarization singularities. Throughout the book, Senthilkumaran presents an explanation of structured optical fields with localized and extended singularities and discusses vortices which carry angular momentum at a level thatrequires minimal mathematics and numerical modeling techniques. Experimenters working in holography, interferometry, metrology, diffractive optics and polarization optics will all benefit from the broad perspective given on this subject and the numerous illustrations. This book targets readers who know physics but aren’t familiar with optical phase singularities and want a thorough introduction to the topic.
