Computational imaging has the potential to revolutionize optical imaging by providing wide field-of-view and high-resolution capabilities. Joint reconstruction of amplitude and phase—known as "coherent imaging or holographic ...
Coded aperture imaging (CAI) is another incoherent imaging technique developed in the 20th century to achieve lensless 2D imaging with nonvisible wavelengths. In CAI, the light from an object is modulated by a coded mask ...
Modern-day technologies like optical computing, integrated photonics, and digital holography require light signals to be manipulated in three dimensions. To achieve this, it is necessary to be able to shape and guide the ...
In the era of big data, global data volume is growing exponentially. The development of numerous technologies depends on massive data and also generates massive data. Data mining, storage, and protection are becoming increasingly ...
Red tides, caused by Karenia brevis blooms, are a recurring problem in the coastal Gulf of Mexico. The organism, Karenia brevis, produces toxins that can cause fish kills, respiratory irritation in humans and cause death ...
Optical manipulation and applications involve numerous fields, such as physics, information, materials and life sciences. It has been included in the national "14th Five-Year Plan" major engineering and projects. To better ...
As an indispensable tool for observing the microcosmos, optical microscopy has boosted the development of various fields, including biology, medicine, physics, and materials. However, optical diffraction imposes a spatial ...
Metasurfaces are highly versatile for manipulating the amplitude, phase, or polarization of light. During the last decade, metasurfaces have been proposed for a vast range of applications—from imaging and holography to ...
The use of light to produce transient phases in quantum materials is fast becoming a novel way to engineer new properties in them, such as the generation of superconductivity or nanoscale topological defects. However, visualizing ...
There is a long-standing folk art in China called "rice carving," in which lifelike artistic patterns are carved on rice with a length of only about 5 mm. These works need to be appreciated with a magnifying glass.
