Preface

The aim of this book is to provide a broad range of topics on interferometry. The topics include some modern techniques, recent approaches to solve issues with a technique, applicability of interferometry in novel scenarios, as well as analytical

In recent times, the application of interferometry has broadened. With that in mind, an overview of updates and recent contributions is provided in Chapter 1, the introductory chapter. It is intended to highlight the significance of recent works as well, with emphasis on connections between other scientific areas of research that have been key to the relevance of the technique. In Chapter 2, radial shearing interferometer is discussed. Chapter 3 describes a detailed method to differentiate superposition principle from measurable superposition effects. Fiber-optic ring resonator is discussed in Chapter 4. Chapter 5 highlights modal interferometers based on a tapered special photonics crystal fiber for highly sensitive detection. Finally, in Chapter 6, application of interferometry in biological systems is addressed through
