A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

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 ...
