Dyeing of Jute Fabric by Eucalyptus Bark Extract
Autor: Dibyendu Bikash Datta, Anindya Majumdar, Debasish Das
Publikováno v: Journal of Natural Fibers, Vol 19, Iss 15, Pp 11030-11035 (2022)
Traditional dyeing procedures were used to color jute fabrics using a natural dye extracted from eucalyptus bark. A pre-mordanting method was followed to dye the jute fabric in the absence and presence of mordant. Alum, vinegar, copper sulfate (CuSO4

Lantana camara flowers as a natural dye source for cotton fabrics
Autor: Dibyendu Bikash Datta, Debasish Das, Biswajit Sarkar, Anindya Majumdar
Publikováno v: Journal of Natural Fibers, Vol 20, Iss 1 (2023)
Environmental concerns about synthetic dyes and their carcinogenic properties renewed interest in eco-friendly natural dyes. Natural dyes produce a wide range of tints and shades with the same dye material. In this study, natural colorants from Lanta

Statistical studies on optical vortices in dynamic speckle fields
Autor: Anindya Majumdar, Sean J. Kirkpatrick
Publikováno v: Journal of Biomedical Photonics & Engineering, Vol 4, Iss 2 (2018)
New parameters to statistically describe and differentiate between different decorrelation behaviors in dynamic speckle fields are described. These decorrelation behaviors are surrogate descriptors of the dynamics of the underlying processes in objec

Spatial Poincaré Plots as Descriptors of Speckle Pattern Second-Order Statistics
Autor: Anindya Majumdar, Sean J. Kirkpatrick
Publikováno v: Journal of Biomedical Photonics & Engineering, Vol 3, Iss 3 (2017)
It is demonstrated herein that the use of spatial Poincaré plots provides an efficient means to describe short and long-range correlations in the spatial structure of the measured intensity distribution of scattered coherent fields. The intensity di

STUDY OF NON-RECIPROCAL DICHROISM IN PHOTONIC STRUCTURES
Autor: Anindya Majumdar
Non-reciprocal phenomena are widely used in photonic devices. Important applications such as isolators and circulator waveguide structures depend on non-reciprocal effects. The basis of these phenomena is a difference in phase or refractive index for

Ellipticity imaging for visualizing and quantifying long and short range correlations in laser speckle data II: phantom and animal studies
Autor: Arkady S. Abdurashitov, Olga A. Sindeeva, Anindya Majumdar, Valery V. Tuchin, Ivan V. Fedosov, Oleg V. Grishin, Kosar Khaksari, Sean J. Kirkpatrick
Publikováno v: Proceedings of SPIE. 2019. Vol. 10877 : Dynamics and fluctuations in biomedical photonics XVI. P. 1087705-1-1087705-11
We present an alternative approach for using dynamic laser speckle data to quantify biophysical dynamics including ordered flows and random motions. The approach yields images that superficially resemble traditional laser speckle contrast images, but
