INTERFERENCE SYSTEM AND AN INTERFERENCE METHOD

摘要

An interference system, comprising:
an interference apparatus, configured such that input light pulses interfere at an interference component;wherein the input of said interference apparatus is provided by a phase-randomised light source, said phase-randomised light source comprising:at least one slave light source;at least one master light source configured to intermittently generate master light pulses such that the phase of each master light pulse has a random relationship to the phase of each subsequently generated master light pulse, further configured to supply said master light pulses to the slave light source; anda controller, configured to apply a time varying drive signal to said at least one slave light source such that just one slave light pulse is generated during each period of time for which a master light pulse is received, such that the phase of each slave light pulse has a random relationship to the phase of each subsequently generated slave light pulse.
