The bounds on the sensitivity and resolution of moiré deflectometry caused by diffraction effects are derived from the wave equation. It is shown that Fresnel diffraction is a necessary and sufficient framework for treating these effects. Expressions are given for angular resolution, spatial resolution, and dynamic range. The proper selection of experimental parameters involves a trade-off between the angular resolution on the one hand and spatial resolution and dynamic range on the other.
