Ptychographic lensless coherent endomicroscopy through a flexible fiber bundle Dataset

This data repository presents representative data of the data we use in the paper "Ptychographic lensless coherent endomicroscopy through a flexible fiber bundle" on the study of the USAF-1951 resolution target measurements. It includes a raw dataset of 3,000 measurements used for the reconstruction given in Fig. 2e-h. Directory StructureLED Repository: This repository contains images using an LED to identify the fiber core centers for the sampling of the measurements.  Core reflection Directory: Features back-reflected core measurements captured when illuminating the laser core by core. This dataset is collected without the USAF target at the distal facet, providing baseline data for the core reflection so that it can be removed from the measurements digitally. Measurements Directory: Consists of the raw data for the measurements taken with the USAF target placed at a 700-micron distance. This directory is the core of our dataset, offering raw, unprocessed measurements crucial for the analysis presented in our paper. Contact_LED_transmission: Contains a contact transmission image of the resolution target, captured with the target placed at contact distance and illuminated by an LED from behind. This serves as a reference image for transmission (Fig.2h).Data Usage For more information, refer to Weinberg, Gil, et al.
