Dataset for "Closing the loop in open-source microscopy: Automated focus, scanning, image tiling and resolution calibration on the OpenFlexure Microscope"

This dataset contains calibration images used to test the performance of a microscope.

Data for the thesis "Closing the loop in open-source microscopy: Automated focus, scanning, image tiling and resolution calibration on the OpenFlexure Microscope". The dataset consists of two image collections:

- a collection of sets of images for tiling and stitching together, used to test the effectiveness of a Python tiling program;
- a collection of aligned edge images used to assess the resolution of a microscope.

Subjects:

Mechanical engineering

Robotics and Autonomy

Tools, technologies and methods

Documentation

Data collection method:

The images were all collected automatically on the OpenFlexure Microscope, as described in the respective chapters of the linked thesis, using the included tiling and stitching code and the Bath Open Instrumentation Group's Micat resolution code.

Technical details and requirements:

Please see the Micat documentation for its technical requirements. The included code requires Python 3.8+ and the packages listed in `requirements.txt`.

Additional information:

The tiling and stitching code included here corresponds to commit bd1e0797 in the Git repository. The auto_mtf code corresponds to commit 73c62c44. The code for the usafcal extension to Micat corresponds to commit 4b7aeed3.
