apodization(ap-ŏ-di-zay -shŏn) Any process suppressing the secondary maxima of a diffraction pattern, such as the faint rings around the Airy disk of an optical image; this allows finer detail to be resolved. It may be achieved, for example, by progressively reducing the transmission of the telescope from the center of the aperture to its periphery.

A technique for modifying the response of a surface acoustic wave filter by varying the overlap between adjacent electrodes of the interdigital transducer.
The modification of the amplitude transmittance of the aperture of an optical system so as to reduce or suppress the energy of the diffraction rings relative to that of the central Airy disk.
A mathematical transformation carried out on data received from an interferometer to alter the instrument's response function before the Fourier transformation is calculated to obtain the spectrum.
