Abstract:
We demonstrate an experimental setup utilizing fiber-optic
detection and coupling of scattered light into existing photon
correlation spectroscopy (PCS) and Fabry–Perot (F–P) interferometry
systems. The performance of the fiber coupled F–P as a
high-resolution interferometer is considered in detail. Several
practical issues and limitations are discussed, including the
selection of optic and fiber-optic components, collimation, effects
of the fiber mode structure and core diameter, and alignment issues.
A series of test measurements on standard systems with well known
properties shows that the proposed fiber-optic design meets the
performance expectations for both PCS and F–P instruments and
presents an attractive alternative to the classical pinhole design.
