This research is conducted to solve a functional principle problem in light beam shaping in the field of illumination. Beam-shaping is the process of redistributing the light intensity to meet the application's requirements using secondary optical systems (e.g., refractive lenses). The functional problem is the deviation of the created output light intensity distribution from the expected design objective, which is observed very often in the experimental setups. The output intensity deviations could be due to deviations in the input source intensity. Therefore, the focus is to develop a secondary lens design approach to perform beam-shaping. This design approach reduces the dependency relationship between the input source intensity distribution and the created output target intensity distribution. This thesis deals with modeling, designing, simulating, and testing several secondary lenses. The current state-of-the-art design approaches are overviewed, and practical examples are used to present the source-target dependency problem. Both analytical and numerical methods are discussed to perform light beam shaping in different levels of complexity. The main contribution of this thesis is the development and testing of a combined design approach for creating freeform lens-arrays (working almost independently of the light source intensity distribution). Results show the ability to perform light beam-shaping, almost independent of the light source intensity distribution. This could be achieved by combining two design approaches in designing freeform lens-arrays to redistribute and superimpose the light intensity. The source-target independence relationship leads to the ability to consider the input light source intensity as a uniform intensity distribution taking into account the number of freeform lens-lets. The independence relationship could be improved by increasing the number of the superimposed light distributions by increasing the number of freeform lens-lets. The increment of the freeform lens-lets should be performed considering the fabrication limits. The optical function of the designed freeform optics is evaluated numerically using the lab software ZEMAX-OpticStudio and experimentally using the lab testing setups. Finally, several application examples are investigated considering the combined design approach.

Download Nonimaging Optics Book in PDF, ePub and Kindle
From its inception nearly 30 years ago, the optical subdiscipline now referred to as nonimaging optics, has experienced dramatic growth. The term nonimaging optics is concerned with applications where imaging formation is not important but where effective and efficient collection , concentration, transport and distribution of light energy is - i.e. solar energy conversion, signal detection, illumination optics, measurement and testing. This book will incorporate the substantial developments of the past decade in this field. * Includes all substantial developments of the past decade in the rapidly moving field of nonimaging optics* The only authoritative reference on nonimaging optics, from the leader in the field

Download Fabrication of Complex Optical Components Book in PDF, ePub and Kindle
High quality optical components for consumer products made of glass and plastic are mostly fabricated by replication. This highly developed production technology requires several consecutive, well-matched processing steps called a "process chain" covering all steps from mold design, advanced machining and coating of molds, up to the actual replication and final precision measurement of the quality of the optical components. Current market demands for leading edge optical applications require high precision and cost effective parts in large volumes. For meeting these demands it is necessary to develop high quality process chains and moreover, to crosslink all demands and interdependencies within these process chains. The Transregional Collaborative Research Center "Process chains for the replication of complex optical elements" at Bremen, Aachen and Stillwater worked extensively and thoroughly in this field from 2001 to 2012. This volume will present the latest scientific results for the complete process chain giving a profound insight into present-day high-tech production.

Download Astrophotonics Book in PDF, ePub and Kindle
Written by well-known scientists in the field with vast experience in teaching astrophotonics, this is the first book to bridge astronomy and photonics for the benefit of developing new astronomical instrumentation. The textbook is clearly structured and covers four main methods relevant to observational astronomy: adaptive optics, photometry, interferometry and spectroscopy. It follows a progressive didactical path in photonics, starting from fundamentals of wave- and micro-optics and developing step-by-step the formalisms required for the treatment of optical multilayers, fiber optics and diffraction/holographic gratings. This approach allows students with a physics/engineering background to learn about the problematic of observational astronomy, while, conversely, students of astronomy are exposed to topics in modern photonics. Each chapter is divided into three main sections devoted to the discussion of astronomical concepts required to size an instrument designed for the particular method, the photonic concepts that most suit that instrument, and an analysis of existing, related photonic instruments. A set of exercises and a bibliography complete each chapter. Appendices include a short review of fundamentals of wave optics and photon detectors, plus an overview of project design and management using a real-life example of an astronomical instrumentation project. With its review of the latest instrumentation and techniques, this is invaluable for graduate and post-graduate students in astronomy, physics and optical engineering.
