A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...
Researchers have developed plasmonic plastic -- a type of composite material with unique optical properties that can be 3D-printed. This research has now resulted in 3D-printed optical hydrogen ...
Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...
A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.
