When it comes to “phase measurement” or “quantitative phase imaging”, many people will
automatically connect them with “laser” and “interferometry”. Indeed, conventional …

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

Digital holographic microscopy (DHM), which combines digital holography with optical
microscopy, is a wide field, minimally invasive quantitative phase microscopy (QPM) …

Gallium nitride (GaN) light-emitting-diode (LED) technology has been the revolution in
modern lighting. In the last decade, a huge global market of efficient, long-lasting, and …

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 …

Micro-light-emitting diodes (μLEDs) are getting much attention in display industry because of
their outstanding optical and electrical characteristics. μLEDs have several advantages over …

The ubiquitous distribution and international connectivity of smartphones is changing the
concept of mobile health and promising to reshape the biosensor market. Smartphone …

High-resolution optical microscopy has traditionally relied on high-magnification and high–
