1 giorno fa · Chromatic pupillometry has been performant in retrospective studies aiming to detect glaucoma, with a sensitivity and specificity up to 95.6% and 94.2% respectively at advanced stages [53, 55 ...
3 mag 2024 · In this sense, one study reported an average longitudinal chromatic aberration of 1.82 D over a range of 420 to 660 nm 56, being 1.26–1.33 D for a range of 450 to 650 mm according to other ...
30 apr 2024 · This article proposes a line scanning chromatic confocal sensor to solve the problem of limited chromatic confocal measurement due to the small measurement range and low measurement efficiency in the industrial inspection process.
4 giorni fa · The detection of chromatic effects of microlensing, neither supports the presence of BHs. Detailed statistical studies of the observed microlensing magnifications and events frequency impose strict upper limits to the fraction of total mass of BHs ($\ltsim$ 1\%) from $10^{-7}M_\odot$ to indefinitely large masses.
14 mag 2024 · The basic concept of chromatic aberration will be introduced as well as the disruptions it may cause to vision and methods by which to measure chromatic adaptation. Additionally, the webinar will explore clinical applications of chromatic aberration and its relationship with myopia.
6 mag 2024 · We verify the proposed strategy by cascading the chiral anisotropic optical media of specifically designed helical pitches and initial director orientations. By this means, planar lenses with RGB achromatic, enhanced chromatic aberration and color routing properties are demonstrated.
7 ore fa · Just like a human engineer would do in inspection process, the machine vision inspection process consists of two steps: Imaging (the “seeing”) and analyzing (the “thinking”); the latter requires a stable software and computing power, together with an algorithm that has defining parameters for errors, like the diameters of irregularities, or chromatic data for discolors.
