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

In the past two decades or so, there has been a renaissance of optical microscopy research
and development. Much work has been done in an effort to improve the resolution and …

Optical image sensors are 2D arrays of pixels that integrate semiconductor photodiodes and
field effect transistors for efficient photon conversion and processing of generated electrons …

Recently, lens-free imaging has evolved as an alternative imaging technology. The key
advantages of this technology, including simplicity, compactness, low cost, and flexibility of …

Light scattering is a fundamental property that can be exploited to create essential devices
such as particle analysers. The most common particle size analyser relies on measuring the …

Although vast research has been performed on biosensors, the materialization of low-cost
