Soft tunable diffractive optics with multifunctional transparent electrodes enabling integrated actuation

optics of diffractive multifocal iol

the diffractive multifocal iol provides simultaneous bifocal imaging by utilizing both diffractive and refractive optics. in both distant and near vision, there is a clear highly focused image on the retina. the second image is highly defocused, providing only faint background illumination. a small amount of the light goes to the higher orders of diffraction which are not perceptible by eyes. t...

The Diffractive Achromatull Spectrum Computational Imaging with Diffractive Optics

Diffractive optical elements (DOEs) have recently drawn great attention in computational imaging because they can drastically reduce the size and weight of imaging devices compared to their refractive counterparts. However, the inherent strong dispersion is a tremendous obstacle that limits the use of DOEs in full spectrum imaging, causing unacceptable loss of color fidelity in the images. In p...

Diffractive Nonlinear Geometric Optics with Rectification

This paper studies high frequency solutions of nonlinear hyperbolic equations for time scales at which diiractive eeects and nonlinear eeects are both present in the leading term of approximate solutions. The key innovation is the analysis of rectiication eeects, that is the interaction of the nonoscillatory local mean eld with the rapidly oscillating elds. The main results prove that in the li...
