High-resolution distance measurement by dynamical spectral filtering of a superluminescent source

Abstract:
A nonincremental interferometer is shown in which the dynamical spectral filtering of a superluminescent source induces a broadband sinusoidal frequency modulation. The method reaches very high resolution limits in distance measurements (a theoretical expectation of 10(-12) m/ radicalHz is obtained) while maintaining all the advantages of heterodyne phase-recovery processing. Comparison with other nonincremental interferometric approaches is given.
