On the “unreasonable” effectiveness of transport of intensity imaging and optical deconvolution

Abstract

The effectiveness of reconstructive imaging using the homogeneous transport of intensity equation may be regarded as “unreasonable,” because it has been shown to significantly increase signal-to-noise ratio while preserving spatial resolution, compared to equivalent conventional absorption-based imaging techniques at the same photon fluence. We reconcile this surprising behavior by analyzing the propagation of noise in typical in-line holography experiments. This analysis indicates that novel imaging techniques may be designed that produce high signal-to-noise images at low radiation doses without sacrificing spatial resolution.
