dc.description.abstract |
In this paper the construction of full-field (imaging) interferometers using infinity corrected
optics commonly used in microscopy is discussed, with an emphasis on self-mixing
interferometry configurations where the imaged light field is mixed with itself rather than
a reference wave. Such configurations are used in speckle shearing interferometry, flow
visualisation and quantitative flow measurement. The critical considerations for constructing
path-length imbalanced full-field interferometers for these and similar applications are
discussed, expressions are derived for key calculations and interferograms from example
interferometers are presented. These include the concept of balancing the infinity-spaces of
the two arms via the use of a glass block to minimise the optical path difference variation
across the interferogram and ensure adequate sampling of the fringes on the detector. Further,
the use of tilted glass blocks in single-pass and double-pass arrangements is detailed for
the generation and control of spatial carrier fringes without extensive realignment of the
interferometer, and for phase shifting. |
