We consider the problem of recovering the phase distribution of a 3D object under coherent illumination using the Transport of Intensity Equation (TIE), which can reconstructs phase information from intensity measurements. To acquire the intensity-information, we records focus changes during a focus sweep using an event sensor. We recover the phase distribution by solving the TIE parameterized by the events. Our method does not require intensity images, leading to time-efficient measurements. |
