Abstract
One of the directions of development in quantitative phase imaging is to provide the capability to reconstruct the phase or preferably refractive index (RI) distribution within thick, highly scattering samples. This direction coincides with current trends in biology, where three-dimensional (3D) organoids are currently replacing standard 2D cultures as more physiological models for tissue growth and organ formation in a dish. The biological complexity of these 3D structures makes the imaging and RI reconstruction particularly challenging, and thus calibration as well as validation structures are important and sought-after tools in instrumentation development. For this reason, in this work, we present the full preparation and measurement procedure for organoid phantoms printed with two-photon polymerization along with the method to obtain the ground truth of the object structure independently of RI reconstruction errors and artifacts.
