Abstract

In lensfree microscopy, the sample is placed close to the image sensor without any imaging lenses in between. This configuration provides the benefits of low cost and compact hardware assemblies as well an ultra-large field of view and a high space-bandwidth product. Image focusing and reconstruction are performed computationally, relying on algorithms such as pixel superresolution and the angular spectrum method of propagation. We present recent progress on improving the resolution to characterize nanoscale materials, protein sensing, ultrafine air pollution monitoring, and high resolution incoherent (fluorescent) imaging.
