Waves and optics: distinguish unequal beams from lost coherence
Compare optics texts, derive unequal-beam fringe visibility, then average a specified random phase while distinguishing fields from intensities.

Who this book is for
For students in the later part of a physics bachelor’s degree or beginning a master’s programme who want to understand the hierarchy of optical approximations. The book offers a free bridge from electromagnetic foundations to imaging models. Its value lies in comparing what each model can explain and where an apparently successful ray picture stops being sufficient.
Prerequisites
Electromagnetism including Maxwell’s equations, calculus, complex amplitudes and elementary linear algebra. Prior introductory optics is useful before the more detailed wave and imaging analysis.
What it covers
Geometrical and paraxial models lead into polarization, interference, coherence and diffraction, with imaging and laser ideas as applications. This progression connects convenient approximations with underlying wave behaviour and the limitations on resolving fine structure.
How to use it
Start with a simple imaging arrangement and state the assumptions needed for a ray calculation. Then ask which feature would require a wave description instead. Follow a polarization state through a short sequence of optical elements using both a diagram and matrices. Compare a predicted resolution or interference pattern with the physical information that the model includes or excludes, checking units and limiting cases.
