This book presents a new didactical approach to the study of optics. It
emphasizes the importance of elaborate new experimental demonstrations
containing pictorial illustrations, computer simulations and models of
optical phenomena in order to ensure a deeper understanding of wave and
geometric optics. It includes problems focused on the pragmatic needs of
students, secondary school teachers, university professors and optical
engineers. A substantial part of this volume is devoted to thermal
radiation and its properties, especially with partial coherence. The
book contains detailed descriptions of demonstrational experiments.
