Ring interferometer with an arrangement to eliminate false indications

摘要

A ring interferometer which has a light waveguide with two ends which act as the two separate coupling points so that light from a source can be coupled into each of the ends to travel in the light waveguide to be uncoupled from the opposite end as an output beams characterized by the source of light emitting light pulses whose duration is smaller than the transit time of the light in the light waveguide and whose time interval between pulses is greater than the transit time.
