Hartmann Wavefront Sensor for X-Ray Optics

Hartmann sensors are a common tool to investigate the wavefront shape of an incoming X-ray beam, as they provide advantages like achromaticity and large dynamic ranges. In this use case, we follow the work of de La Rouchefouauld O. et al. [Sensors 2021, 21, 874.], to model the X-ray fields propagating through the Hartmann wavefront sensor, which is composed of a series of pinholes. The diffraction from each pinhole will lead to a shift at the detector plane which can be used to calculate the wavefront of the input.
