Paper Abstract
The effect of measurement noise on the phase reconstruction is here analyzed for curvature sensors. It is shown,
that for a fixed extra-focal distance the phase variance depends only on the number of photons and is independent
of the number of sensing elements.
The error propagation factor is further computed for three different sampling geometries: square and hexagonal
grids and the polar geometry commonly used for curvature sensors. The error propagation factor is seen to
be almost independent of the grid geometry.
