Taking as its starting point a holographic interferometric
technique, used to measure the static and dynamic bulk moduli
of elastomers, this thesis describes the progression of
research aimed at extending the range and nature of these
measurements. The use of Electronic Speckle Pattern
Interferometry (E.S.P.I) as an alternative optical technique
is described. The use of amplitude and phase modulation
within this interferometer is also described.
These modulation techniques are shown to be advantageous in
manipulating fringe distributions making data extraction
easier and more accurate. This allows measurement, over an
extended frequency range, of the pressure and temperature
dependence of bulk moduli and also Young's moduli for
elastomer samples. The visco-elastic components of these
moduli are also investigated by using E.S.P.I. to measure the
loss component tan σ of the vibrational response of the
elastomer.
