We review basic principles of modern optical magnetometers, discuss fundamental limitations on their performance, and describe recently explored applications for dynamical measurements of ...

They’re full of fascinating engineering, but for my money, the inline optical repeaters that boost the signals along the way are the most interesting bits, even though — or perhaps especially ...

All zoom lenses in film cameras and digital single lens reflex (DSLR) cameras are optical zoom. Digital point-and-shoot cameras as well as consumer and prosumer video camcorders have optical zoom ...
