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 ...

A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

SPADs employ an avalanche process to generate significant current from a single photon. That results in higher power ...

Eliminating the need for a separate magnetic lid sensor, the CM36262 integrates a patent-pending optical lid sensor with an ambient-light sensor (ALS) and proximity sensor, thus simplifying the design ...
