<p>This thesis demonstrates a measurement of a plasma fluctuation
velocity-space cross-correlation matrix using laser induced fluorescence.
The plasma fluctuation eigenmode structure on the ion velocity distribution
function can be empirically determined through singular value decomposition
from this measurement. This decomposition also gives the relative strengths
of the modes as a function of frequency. Symmetry properties of the matrix
quantify systematic error. The relation between the eigenmodes and plasma
kinetic fluctuation modes is explored. A generalized wave admittance is
calculated for these eigenmodes. Since the measurement is a localized
technique, it may be applied to plasmas in which a single point measurement
is possible, multipoint measurements may be difficult, and a velocity
sensitive measurement technique is available.
