Abstract:
Interference is a fundamental physical phenomenon proving the wave nature of energy. It is based on wave superposition forming natural waveeffects expressed both in nature under random selective conditions as well as in laboratory scientific experiments by carefully controlled selection of parameters. Science generates a number of technology applications using the inherited properties of waves after their superposition in space termed interference. These interfering waves have extremely rare properties compared to their initial physical systems and become entities with measurable quantities which can be used to quantify qualities in other phenomena, mechanisms, and physical objects with variety of physical properties. These waves are currently fully explored in theoretical and experimental physics finding many modern applications and enlightening the way to longstanding questions. Remote non contact study of surfaces and their reactions visually witnessing internal subsurface and unknown bulk information without need to implement destructing forces or penetrating irradiation to trace them and without interacting with it or interfering with the results is one of the most challenging modern applications of interference physics. Apart from everyday life applications artworks’ conservation is a field that interference properties are uniquely suited. It is the quality of light wave interference that is being utilised in this body of research and summarised in the present thesis. The context of the presented thesis unfolded in next chapters is constructed in one book on a contextual rather than chronological order. The contextual base presentation is achieved through clustering same context published articles that have resulted over the course of years of research which have been published in review journals, conference proceedings or governmental publications. The formation of laser interference fringe patterns and their exceptional qualitites in application for structural diagnosis with defect detection and definition, their unique properties utilised in studies of environmental and climate effects, the prototype optical geometries and novel experimental methodologies envisaged to solve specific application problems are presented along with examination on theoretical matters of exploring interference properties, qualities, geometries and their outmost final product the interference fringe pattern. Thus in this thesis the aim is to prove the contribution of the experimental research publications to the study of interference patterns as a highly sophisticated structural diagnostic tool in the complicated problems of Cultural Heritage applications. The implementation of interference phenomena and the development in experimental investigations applied in inhomogeneous, anisotropic, shape variant, multilayered, multicomposition cultural heritage objects, paves the way to implement “fringe patterns” as a scaleless (scale independent) diagnostic detector allowing generation of novel tools and practices on problem solving projects. The developments are beyond the specific application and are extended to other fields of science and technology. The articles and bibliography cited within the text including author's publications utilised as sources in the writing of this thesis are referenced in square brackets and are explicitly listed in ANNEX I The list of publications of the author is shown in ANNEX II. The originals of author's publications supporting the thesis are provided after the Annex II as have been published. Due to limitation in number of pages there is not included a section to present the fundamental principles of the phenomena presented here instead a list of books commonly found in most University libraries is provided for interested readers as BIBLIOGRAPHY at the last paragraphs of ANNEX I.
