Two deflection techniques for the measurement of the
dispersive properties of an optical medium have been implemented. Prismatic
deflection is used to measure the dispersion of a medium exhibiting Electromagnetically
Induced Transparency (EIT) with
the 
cascade system in 85Rb
and 87Rb.
In addition, the dispersion associated
with a saturated absorption and hyperfine pumping spectrum is measured
by deflection due to a spatial inhomogeneity of the
refractive index induced by an expanded Gaussian-profile pump beam.
