Investigation of statistical variations between lenslet of microlens arrays

open access: yes, 2022
S.4438-4445We investigate the behavior of microlens arrays consisting of lenslets that have statistically distributed parameters (Focal length, offset phase, lens centre). In theoretical investigations we introduce a lens array coherence parameter Kappa,

Edge Analysis of Optical Coherent Tomography Image by Statistical Methods

open access: yesIndian Journal of Applied Research, 2011
The role of optical coherent tomography image is important for the diagnosis of retina layers in ophthalmology. Here OCT image is subject to computed by edge detection methods. The output of edge detection is applied to standard statistical techniques of Entropy, Kurtosis, slew, Standard deviation and variance.

Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning

open access: yesAdvanced Engineering Materials, EarlyView.
The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.
