摘要
A low-coherence reflectometer for use in measuring optical backscattering. The invention utilizes an optical attenuation in the reference arm of a Michelson interferometer to reduce the relative intensity noise. The invention obtains essentially the same performance as obtained with balanced detector schemes while maintaining the simplicity of the Michelson interferometer design and increased scan distance.
