The frequent outbreak of global infectious diseases has prompted the development of rapid
and effective diagnostic tools for the early screening of potential patients in point-of-care …

Lensless imaging provides opportunities to design imaging systems free from the constraints
imposed by traditional camera architectures. Due to advances in imaging hardware …

The traditional analytical biosensor instruments are relatively bulky, expensive, and not easy
to handle, thus their applications are largely limited in resource-limited settings. The recent …

We report an imaging method, termed Fourier ptychographic microscopy (FPM), which
iteratively stitches together a number of variably illuminated, low-resolution intensity images …

High-resolution optical microscopy has traditionally relied on high-magnification and high–
numerical aperture objective lenses. In contrast, lensless microscopy can provide high …

Point-of-care testing technique is increasingly important for healthcare management in
human being's daily life. However, traditional biosensor systems for health care are …

Improving access to effective and affordable healthcare has long been a global endeavor. In
this quest, the development of cost-effective and easy-to-use medical testing equipment that …

Lens-free on-chip digital holographic microscopy (LFOCDHM) is a modern imaging
technique whereby the sample is placed directly onto or very close to the digital sensor, and …

We report a chip-scale lensless wide-field-of-view microscopy imaging technique, subpixel
perspective sweeping microscopy, which can render microscopy images of growing or …

We report an imaging scheme, termed aperture-scanning Fourier ptychography, for 3D
refocusing and super-resolution macroscopic imaging. The reported scheme scans an …
