Multiphoton Fluorescence Microscopy with GRIN Objective Aberration Correction by Low Order Adaptive Optics
Graded Index (GRIN) rod microlenses are increasingly employed in the assembly of optical probes for microendoscopy applications. Confocal, two-photon and optical coherence tomography (OCT) based on GRIN optical probes permit in-vivo imaging with penetration depths into tissue up to the centimeter range. However, insertion of the probe can be complicated by the need of several alignment and focu...
متن کاملGradient Index (GRIN) optics of the human eye: contributions of Professor Carlos Gómez-Reino Carnota.
In the present issue of Journal of Optometry, the reader will find a paper describing a new approach to derive the contributions of the Gradient Index of the crystalline lens to the optical quality of the human eye. This is just an example of the seeds left by Professor Gómez-Reino in the field of Optics and Optometry. It is difficult to summarize in a few lines the life and career of Carlos Gó...
متن کاملFunctional human GRIN 2 B
We investigated the role of a single nucleotide polymorphism rs3764030 (G>A) within the human GRIN2B promoter in mental processing speed in healthy, cognitively intact, older adults. In vitro DNA‐binding and reporter gene assays of different allele combinations in transfected cells showed that the A allele was a gain‐of‐function variant associated with increasing GRIN2B mRNA leve...
متن کاملBiomimetic Gradient Index (GRIN) Lenses
A new class of hierarchically structured polymer optical materials possessing an internal refractive index gradient that mimics biological optical materials is described. The new materials permit the fabrication of gradient refractive index (GRIN) lenses with an unprecedented variety of index gradients. Gradients with different functional forms in both the radial and axial directions have been ...
متن کاملGeometry-invariant GRIN lens: iso-dispersive contours
A dispersive model of a gradient refractive index (GRIN) lens is introduced based on the idea of iso-dispersive contours. These contours have constant Abbe number and their shape is related to iso-indicial contours of the monochromatic geometry-invariant GRIN lens (GIGL) model. The chromatic GIGL model predicts the dispersion throughout the GRIN structure by using the dispersion curves of the s...
