WebbAbstract The geometrical theory of diffraction is an extension of geometrical optics which accounts for diffraction. It introduces diffracted rays in addition to the usual rays of geometrical optics. These rays are produced by incident rays which hit edges, corners, or vertices of boundary surfaces, or which graze such surfaces. WebbThe theory of optical forces on spherical scatterers is here generalized to arbitrary incident fields. The interaction between spherical harmonics of different order, and the degree and azimuthal parity, is studied in detail. The resulting force from all the contributing components is presented in analytical form.

WebbThe geometrical theory of diffraction (GTD) extends the idea of rays by introducing the concept of diffracted rays that differ from the rays of geometrical optics in that these are produced when a ray (which may, in certain cases, be a diffracted ray itself) hits an edge or a corner of an obstacle, or grazes the surface of the obstacle. All these cases are … Webb1 feb. 2001 · 3.1 Optical Image Formation. In optical image formation, we understand a point source of light to be placed at an object point.

For an ingoing plane wave ei→k ⋅ →r, the wavefunction far away from the scattering region must have the form ψ→k(→r) = ei→k ⋅ →r + f(θ, φ)ei k r r. where θ, φ are measured with respect to the ingoing direction.
