Optical Trapping by Aperiodic Kinoform Lenses Based on the Baum–Sweet Sequence

Photonics
This work presents a new family of aperiodic diffractive lenses based on the Baum–Sweet sequence. To the best of our knowledge, this is the first report of a diffractive lens derived from this sequence.

DESIGN OF THE MULTIORDER INTRAOCULAR LENSES

Приборы и методы измерений, 2015
Intraocular lenses (IOLs) are used to replace the natural crystalline lens of the eye. Just few basic designs of IOLs are used clinically. Multiorder diffractive lenses (MODL) which operate simultaneously in several diffractive orders were proposed to ...

Diffraction analysis of lens axicons

, 2005
Axicons, as shown in Fig. 1(a), are optical elements that produce long and narrow focallines along the optical axis, rather than the conventional focal point created by a lens. Thefocal line can be used for e.g. alignment, extending the focal depth of existing methods, orparticle trapping and transportation.
