Lens-free imaging is a cutting-edge imaging technique that allows for high-resolution, wide-field imaging without the need for traditional lenses. Instead, it uses computational algorithms to reconstruct images directly from the light patterns recorded by a sensor. This technology has the potential to revolutionize medical diagnostics, environmental monitoring, and other fields where high-resolution imaging is essential. Lens-free imaging offers advantages such as compactness, cost-effectiveness, and the ability to capture large areas with a single exposure.
