Development of Simple and Affordable Integrating Device for Accurate LED Strip Light Measurement

Sensors
LED strips are increasingly used as lighting sources in public and private spaces. However, traditional photometric methods, such as integrating spheres, are unsuitable for measuring their light parameters, often resulting in significant errors and ...

Mass Photometry

Annual Review of Biophysics
Mass photometry (MP) is a technology for the mass measurement of biological macromolecules in solution. Its mass accuracy and resolution have transformed label-free optical detection into a quantitative measurement, enabling the identification of distinct species in a mixture and the characterization of their relative abundances. Its applicability to a

The Status of the Astrophysical Parameters of Upper Main Sequence Stars

Astronomy
Calibrating the ages, masses, and radii of stars on the upper main sequence depends heavily on accurate measurements of the effective temperature (Teff) and surface gravity (logg).

Current and Future Applications of Reverberation-Mapped Quasars in Cosmology

Frontiers in Astronomy and Space Sciences, 2019
Reverberation mapping technique (RM) is an important milestone that has elevated our understanding of Active Galactic Nuclei (AGN) demographics, giving information about the kinematics and the structure of the Broad Line Region (BLR).

Investigation of the optoelectronic properties of a novel polypyrrole-multi-well carbon nanotubes/titanium oxide/aluminum oxide/p-silicon heterojunction

Nanotechnology Reviews
The novel design of gold/polypyrrole-multi-walled carbon nanotubes/titanium dioxide/aluminum oxide/P-type silicon/aluminum (Au/PPy-MWCNTs/TiO2/Al2O3/p-Si/Al) is utilized to fabricate supercapacitors, sensors, diodes, and microelectronic devices.

TSI modeling: A comparison of ground-based Ca II K-line data with space-based UV images from the SDO/AIA instrument

Journal of Space Weather and Space Climate
The Total Solar Irradiance (TSI) is an important input for the Earth’s climate. To describe the competing contributions of sunspots and faculae on irradiance variability, the San Fernando Observatory (SFO) irradiance model has two components: One ...

Theoretical formulation and experimental validation of brightness evaluation using digital cameras

Results in Optics, 2021
In this study, we formulated the brightness relation of two digital photos captured by a single digital camera and verified it experimentally. The experimental results suggested that the used zoom lens has an intrinsic error, thereby making accurate ...
