Tom Potter--

A phono cartridge might work for small variances in test surface--the
voltage out would be proportional to the mechanical deflection of the
needle (variance of test object). Would need O scope and might have to
integrate voltage changes with respect to time/distance if you want to
plot the surface.

Good luck
