Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...

Abstract: In order to solve the problem that there is no uniform test method and calibration platform for PD optical sensors, this paper takes the light guide rod as the object and simulates it in ...

Abstract: A lightweight portable DC charger on-site calibration instrument based on DC comparator technology was studied to address the difficulties in equipment handling, complex operation wiring, ...
