The singularities of light: intensity, phase, polarisation

open access: yesLight: Science & Applications, 2023
In modern optics, light can be described at different levels: as rays, as scalar waves, as vector fields, and as quantum fields. In the first three levels, there are singularities—characteristic features, useful in interpreting phenomena at that level ...

Impact of light intensity or choice of intensity on broiler performance and behavior

open access: yesJournal of Applied Poultry Research, 2022
SUMMARY: The optimal light intensities for broiler production and well-being have been investigated for some time. The use of a minimum 20 lux (lx) is mandated within the European Union (European Commission, 2000; European Union 2007).

Skylight Light Intensity Data Logging System

open access: yesActive and Passive Electronic Components, 1997
The design of a skylight intensity data logging system is presented. The proposed system is able to accept 32 inputs in two 16 input blocks with capabilities for further expansion. A typical application would be to simultaneously monitor real time change
