LIGHT VELOCITY MEASURING INSTRUMENT

This instrument partly forms by optical system and the signal processing system. It is designed according to the light beat frequency principle, and waveform and phase of the light beat frequency wave of Tao different optical paths can clearly be observed through oscilloscope.

Its design is reasonably, and it is new and original to work out the plot, and the structure is compact, and his forming a complete set or system instrument all is the instrument in common use in the laboratory, and especially is fit for modern physics teaching experiment in college.
