Scientific paper

We define a new observable that depends on finite redshift differences of the
spin-weighted angular moments of the two point function of the three
dimensional cosmic shear and on luminosity distance. It is shown that precise
measurements of our observable will be able to tightly constrain the expansion
history of the universe.
