Use of clinic refractometer at farm as a tool to estimate the IgG content in goat colostrum
Journal of Applied Animal Research, 2018 Refractometry has been proposed as a farm technique to estimate the IgG concentration in colostrum. In order to validate the method in goat colostrum using a clinical refractometer, 216 colostrum and milk samples were obtained from 54 dairy goats ...

Simple refractometry using optical path separation via multiple pinholes
, 2017 We herein report on a simple and novel method of refractometry that uses a micro image defocusing technique. This simple method makes use of a three-pinhole aperture attached to a microscopic optical system.

Fourier-Transform-Based Metrology for Whispering Gallery Mode Spectra in Soft Photonic Microcavities
MetrologyWe present a Fourier-transform (FT)-based framework for quantitative analysis of whispering gallery mode (WGM) spectra in soft photonic microcavities. By treating the WGM spectrum as a quasi-periodic signal, the method enables robust extraction of the ...

Refractometry by total reflection
, 1987 Refractometry is a means to measure the refractive indices of liquids, gases, and dielectric solids, either isotropic or anisotropic, by observation of light refraction or reflection with a microscope, refractometer or other more specialized equipment ...

Refractometry of microscopic objects using digital holography [Elektronisk resurs]
, 2003 Digital holography has some desirable properties for refractometry of microscopic objects since it gives phase and amplitude information of an object in all depths of focus from one set of exposures.

Improved Filters for Angular Filter Refractometry
, 2023 Angular filter refractometry is an optical diagnostic that measures absolute contours of line-integrated density gradient by placing a filter with alternating opaque and transparent zones in the focal plane of a probe beam, which produce corresponding ...
