Hamiltonian optics

Hamiltonian optics is a type of physics that looks at the way light travels and changes when it passes through different materials. It looks at how light moves in a curved path when it passes through an individual material. It also looks at how light changes when it passes through a combination of several materials, like when light goes through two lenses. Hamiltonian optics uses special equations called Hamiltonian equations to figure out how light will move. Hamiltonian optics can be used to understand how light works in cameras, telescopes and microscopes.
