Light Speed Meter

The Light Speed Meter is an equipment set for determining the speed of light, thanks to electronic run-time measurement. The set comprises a compact housing containing a transmitter emitting short LED pulses, a photo receiver and a calibrated, oscillating quartz generator that produces chronologically precise square-wave pulses. 

Emitted light pulses are returned by an internal reflector and by a triple-prism reflector placed a long distance from the light source. The returning light signals are then superimposed on the original signal. A dual-channel oscilloscope is used to measure the time difference between the two signals, and the speed of light can be calculated from this difference and the distance to the triple-prism reflector. The triple-prism reflector itself can be installed by eye without the need for complex adjustments.
