Image-forming systems: Matrix formulation of the optical invariant via Fourier optics

Mostrar todas las versiones(2)

In this paper we consider Fourier optics and from it we obtain the expression for the optical invariant valid for any image-forming system. The invariant that we derive is applicable to systems which are or are not centred or symmetrical and therefore it is written in a matrix form. When the paraxia...

Sumario:In this paper we consider Fourier optics and from it we obtain the expression for the optical invariant valid for any image-forming system. The invariant that we derive is applicable to systems which are or are not centred or symmetrical and therefore it is written in a matrix form. When the paraxial approximation holds, the optical invariant reduces to the classical Lagrange–Helmholtz invariant. © 1996 Taylor & Francis Group, LLC.
