It covers the derivation of radiated fields, the Fraunhofer approximation for far-field analysis, and the relationship between aperture illumination, gain, and angular resolution.

This can be used as a spectroscopic tool—a diffraction grating disperses light according to wavelength, for example, and is used to produce spectra—but diffraction also limits the detail we can obtain in images.Diffraction limits the resolution in many situations. The acuity of our vision is limited because light passes through the pupil, which is the circular aperture of the eye.
