(Near) Real-Time Snow Water Equivalent Observation Using GNSS Refractometry and RTKLIB [PDF]

Sensors, 2022
Global navigation satellite system (GNSS) refractometry enables automated and continuous in situ snow water equivalent (SWE) observations. Such accurate and reliable in situ data are needed for calibration and validation of remote sensing data and could ...

Evaluation of the agreement between Brix refractometry and serum immunoglobulin concentration in neonatal piglets [PDF]

Animal, 2021
Neonatal piglets lack immunoglobulins at birth. Sufficient colostrum intake (CI) and immunoglobulin absorption are essential for an appropriate passive transfer of immunity via the colostrum.

Material Limitations on the Detection Limit in Refractometry [PDF]

Sensors, 2009
We discuss the detection limit for refractometric sensors relying on high-Q optical cavities and show that the ultimate classical detection limit is given by min {Δn} ≳ η with n + iη being the complex refractive index of the material under refractometric investigation.
