Laser micrometers are capable of measuring outside diameter for mechanical engineering and machining purposes. Within the micrometer is a transmitting unit responsible for emitting a laser beam that ...
We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...
Their measurement protocol combines two distinct laser beams to capture the elusive timing of quantum entanglement formation. To put the scale of these measurements into perspective, consider the ...
