TL;DR: Unique features of lens-free computational imaging tools are discussed and some of their emerging results for wide-field on-chip microscopy, such as the achievement of a numerical aperture of ∼0.8–0.9 across a field of view (FOV) of more than 20 mm2, which corresponds to an image with more than 1.5 gigapixels.

TL;DR: A sub-pixel shifting based super-resolution algorithm is implemented to effectively recover much higher resolution digital holograms of the objects, permitting sub-micron spatial resolution to be achieved across the entire sensor chip active area.

TL;DR: A lensfree on-chip imaging technique that can track the three-dimensional trajectories of > 1,500 individual human sperms within an observation volume of approximately 8–17 mm3 and could in general be quite valuable for observing the statistical swimming patterns of various other microorganisms, leading to new insights in their 3D motion and the underlying biophysics.

TL;DR: This compact and cost-effective fluorescent imaging platform attached to a cell-phone could provide an important tool for wide-field imaging and quantification of various lab-on-a-chip assays developed for global health applications, such as monitoring of HIV+ patients for CD4 counts or viral load measurements.

TL;DR: In this article, a 2D holographic diffraction pattern of each cell or micro-particle on a chip using a high resolution sensor array that has ∼2 µm pixel size is recorded.
