The focusing properties of diffractive lenses designed using the Fibonacci sequence
are studied. It is demonstrated that these lenses present two equal intensity foci and
that the ratio of the two focal distances approaches ...

[EN] We report a scheme for the detector system of confocal microscopes in which the pinhole and a large-area detector are substituted by a CCD camera. The numerical integration of the intensities acquired by the active ...
