ondelette; wavelet

Elementary oscillatory function limited in time and space.

paraxial optics; paraxial

Approximation that consists in integrating the complex amplitude of the electric field on a flat surface.

metaxial optics; metaxial

Approximation that consists in integrating the complex amplitude of the electric field on a spherical cap.

transmittance; transmittance

Specific transfer function characterizing the amplitude transmission of light at each point of an optical system.
