WebThe Lagrange invariant provides a basic description of an optical imaging system. Many important conclusions can be drawn from it. We discovered that the Lagrange invariant is violated in a self-interference holography system with particular characteristics. With a proof-of-principle system, we proved this violation both theoretically and experimentally. …

Violation of the Lagrange invariant in an optical imaging system

Webany optical system comprising only lenses, the product of the image size and ray angle is a constant, or invariant, of the system. This is known as the optical invariant. The result is valid for any number of lenses, as could be verified by tracing the ray through a series of lenses. In some optics textbooks, this is also called the Lagrange ...

WebFor a given optical system, the Lagrange invariant is a constant throughout all space, that is, it is invariant upon refractionand transfer. The optical invariantis a generalization of the Lagrange invariant which is formed using the rayheights and angles of any two rays. For these rays, the optical invariant is a constant throughout all space. [2] WebOther invariants in an optical system can be found, involving finite rays, and, as with the Lagrange invariant, they have physical implications beyond the immediate geometrical optics. It also turns out that they provide neat and simple proofs of certain geometrical optics theorems which are otherwise not so directly proven. This chapter shows ...
