Lensfree Phase Target Dataset for Microscopy Resolution Analysis

Raw lensfree on-chip measurements of a phase resolution target acquired using a maskless LED-array microscope. The dataset includes raw intensity measurements, system parameters, and reconstruction code for coherent phase retrieval and illumination-angle estimation. SHANMUGAVEL, SIBI CHAKRAVARTHY contributed this data to the Texas Data Repository, last updated in December 2025.

Use Cases

• Benchmarking phase retrieval algorithms based on the included raw intensity measurements and reconstruction code.
• Analyzing optical resolution and contrast transfer based on the USAF phase target measurements.
• Calibrating spatially-varying illumination angles in lensfree systems based on the provided calibration data.

Strengths

• Includes raw intensity measurements, system parameters, and reconstruction code in both MATLAB and Python.
• Data is specifically designed for resolution analysis and phase retrieval benchmarking as described in a supporting manuscript.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
