Illuminating the retina with a point-scan system, we measured angle-resolved light that returns from the retina to render 3D phase-contrast and plenoptic imaging of various retinal cells and structures.

All retina-based vision restoration approaches rely on the assumption that photoreceptor loss does not preclude reactivation of the remaining retinal architecture. Whether extended periods of vision loss limit the efficacy of restorative therapies at

Optical scattering measurements of random anti-reflection subwavelength surface structures on binary gratings

Autor: Karteek Kunala, Menelaos K. Poutous, Praneeth Gadamsetti

Publikováno v: Optical Components and Materials XVII.

Random anti-reflection sub-wavelength structures (rARSS) on optical component surfaces have been shown to enhance transmission by reducing Fresnel reflection. These structures have a broadband anti-reflection effect, and insensitivity to high angle o

Optical Scattering of Deterministic Diffractive Elements with Antireflective Structured Surfaces

Autor: Karteek Kunala, Menelaos K. Poutous, Praneeth Gadamsetti

Publikováno v: 2019 IEEE 16th International Conference on Smart Cities: Improving Quality of Life Using ICT & IoT and AI (HONET-ICT).

Diffractive optical elements with complicated multi-layered phase profiles, require the suppression of Fresnel reflections in cascading-component optical systems. Random nanostructures have been shown to reduce Fresnel reflectivity of optical windows
