A new method of determining the optical properties of cotton fibers using polarizing interference microscopy

Abstract

SynopsisThe refractive indices, birefringence, and cross-sectional area of cotton fibers was measured using interference polarizing microscope constructed by M. Pluta. A new technique was suggested by realizing the measurements a t the perpendicular position of the duplicated image of fiber to the interference fringe. The proposed procedure is a combination of modification of Hamza method and Pluta dual wavelength method, and it was possible to measure a t once the three mentioned features of single fiber a t one time.

Interferometric determination of the optical properties of fibres with irregular transverse sections (Ramie)

“…Recently, Zurek & Zakrzewski (1983) suggested a new technique for the measurement of refractive indices, birefringence and cross-sectional area of cotton fibres.…”

Determination of Refractive Index and Material Dispersion of Step Index Optical Fibers Using Variable Wavelength Interferometric Technique

“…Hamza (1980) [4] extended the applications of the Pluta microscope to measure the mean refractive indices and birefringence of fibers with irregular transverse sections. Zurek and Zakrzewski (1983) [5] determined the refractive indices and birefringence of cotton fibers using the Pluta microscope. Hamza et al [6][7][8][9] Used Pluta polarizing interference microscope for different fibers with regular and irregular transverse sections to determine its refractive indices and birefringence.…”
