Miniature optical planar camera based on a wide-angle metasurface doublet corrected for monochromatic aberrations
Optical metasurfaces are two-dimensional arrays of nano-scatterers that modify optical wavefronts at subwavelength spatial resolution. They are poised to revolutionize optics by enabling complex low-cost systems where multiple metasurfaces are lithographically stacked and integrated with electronics. For imaging applications, metasurface stacks can perform sophisticated image corrections and ca...
متن کاملA broadband wide-incident-angle reflective polarization converter
Yan Li (SID Student Member) Thomas X. Wu (SID Member) Shin-Tson Wu (SID Fellow) Abstract — A high-performance reflective polarization converter which could be used in a backlight recycling system for liquid-crystal-display (LCD) devices is proposed. The device consists of a twistednematic (TN) liquid-crystal film, a uniaxial A-plate, and a reflector. The configuration parameters, such as thickn...
متن کاملA programmable metasurface with dynamic polarization, scattering and focusing control
Diverse electromagnetic (EM) responses of a programmable metasurface with a relatively large scale have been investigated, where multiple functionalities are obtained on the same surface. The unit cell in the metasurface is integrated with one PIN diode, and thus a binary coded phase is realized for a single polarization. Exploiting this anisotropic characteristic, reconfigurable polarization c...
متن کاملAchromatic doublet intraocular lens for full aberration correction.
A doublet intraocular lens optimized for both chromatic and monochromatic aberration correction in pseudophakic eyes is presented. Ray-tracing techniques were applied to design the lens in white light within a chromatic eye model. Combinations of two materials, already commonly used in intraocular lenses, as acrylic and silicone, were used. Iterative optimization algorithms were employed to cor...
متن کاملMetasurface holograms for visible light
Holography, a revolutionary 3D imaging technique, has been developed for storing and recovering the amplitude and phase of light scattered by objects. Later, single-beam computer-generated phase holography was proposed for restoring the wavefront from a given incidence. However, because the phase modulation depends on the light propagation inside the material, the thickness of phase holograms u...
