Abstract
Technologies are generally described to recover diffraction limited amplitude and phase images of objects from single shot image plane hologram data. In some examples, an image processor may receive digital hologram data derived from interference between a reference signal and an unknown object image. The image processor may then attempt to recover a version of the unknown object image by minimizing a cost function associated with the reference signal and the digital hologram data. The cost function may include a data-fit cost component and a constraint cost component, and the image processor may iteratively minimize the cost function by alternately minimizing the data-fit cost component and the constraint cost component.
