Pseudo-heterodyne signal processing scheme for interrogation of fiber Bragg grating sensor arrays [PDF]
, 1998 An intensity-based interrogation technique for arrays of fiber bragg grating (FBG) sensors is reported. The technique is based upon each FBG forming one mirror of a Michelson interferometer.

Fibre optic fizeau intererometer for optical coherence tomography [PDF]
, 2006 The aim of the project was to develop the Fizeau interferometer configuration to take advantage of the benefits derived from its “downlead insensitivity” to temperature and polarisation fading.

Comparative signal-to-noise analysis of fibre-optic based optical coherence tomography systems [PDF]
, 2005 Several optical coherence tomography ( OCT) systems are proposed using optical. fibre components and based around Fizeau sensing interferometers. The theoretical signal- to- noise ratio ( SNR) is calculated for each of the proposed configurations ...

Demo 23-20 Michelson Interferometer with White Light [PDF]
, 2001 This demonstration shows white light fringes from a Michelson interferometer using the system shown in Figure 1. When the two optical path lengths are exactly the same the two signals are out of phase, due to the difference in the phase changes at the ...

In-Situ Surface Inspection Using White Light Channelled Spectrum Interferometer [PDF]
We introduce a new environmentally robust optical interferometry system for fast surface profile measurement. The proposed white light channelled spectrum Interferometer (WLCSI) is effective for applications in on-line surface inspection because it ...
