Measurement of chromatic aberration in a Low Energy Electron Microscope (LEEM) or Photo Electron Emission Microscope (PEEM) is necessary for quantitative image interpretation, and for accurate correct...
Aberration correction in transmission electron microscopy has proven feasible and useful over a large range of acceleration voltages. The spherical aberration has been corrected for beam energies from...
We present an optimization design for a stereo-photographic system where achromatic double-prism arrays are used in front of the camera lens to reduce chromatic aberration and distortion. Due to the o...
We measured discrimination thresholds for illumination changes along different chromatic directions starting from chromatically biased reference illuminations. Participants viewed a Mondrian-papered s...
To measure longitudinal chromatic aberration (LCA) of various intraocular lenses (IOLs) and to assess LCA effects on polychromatic image quality with a focus on multifocal IOL designs.
Refractive surgeries can be divided into two distinct categories: 1) corneal surgeries (superficial and deep procedures) carried on the surface of the eye and 2) lens surgeries (phakic IOL...
The goal of the study is to quantify wavefront aberration profiles of the eye with and without contact lens across the visual field. This will enable us to investigate the impact of the ab...
The specific aim of this study is to investigate rod, cone and melanopsin driven pupillary light response in individuals with progressive supranuclear palsy (PSP), age-matched healthy cont...
We have identified focussing problems related to myopia getting worse. Our trial uses optical and orthoptic interventions that correct the focussing problems to see if this retards myopia ...
Retinal blood flow measurement is of scientific and clinical value. For this purpose retinal vessel morphology (such as diameter, vessel wall thickness, etc) determination is crucial. Diff...
The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus (the body) which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.
The use of light interaction (scattering, absorption, and fluorescence) with biological tissue to obtain morphologically based information. It includes measuring inherent tissue optical properties such as scattering, absorption, and autofluorescence; or optical properties of exogenous targeted fluorescent molecular probes such as those used in optical MOLECULAR IMAGING, or nontargeted optical CONTRAST AGENTS.
Imaging techniques that use illumination created with several optical interference filters by which the frequency ranges are spectrally narrowed and light scatter is greatly reduced. Thus the reflected photons reconstituting the images are from distinct depths (the surface and deeper layers) of the object being imaged.
Microscopic imaging techniques that utilize nonlinear responses of light-matter interactions which occur with high-intensity illumination, such as from LASERS, and specialized light signal detection instrumentation to produce images without the need for dyes or fluorescent labels.
Products or parts of products used to detect, manipulate, or analyze light, such as LENSES, refractors, mirrors, filters, prisms, and OPTICAL FIBERS.
