Decollimation

Decollimation: In a beam with the minimum possible ray divergence or convergence, any mechanism by which rays are caused to diverge or converge from parallelism.

Note 1: Decollimation may be deliberate for systems reasons, or may be caused by many factors, such as refractive index inhomogeneities, occlusions, scattering, deflection[?], diffraction, reflection, and refraction.

Note 2: Decollimation occurs in applications such as radio, radar, sonar, and optical communications.
