The rapid evolution of diffractive optical elements (DOEs) is reshaping space telescope design by offering lightweight, compact and high-performance alternatives to conventional optical systems. These ...

The endeavor to detect life on exoplanets is presently constrained by the limitations and logistical complexities inherent in building larger, more sensitive mirror-based space telescopes. A novel ...

Thin, simple diffractive lenses are notorious for their blurry images, so they have never been used in astronomical observatories. But if you could improve their clarity, using diffractive lenses ...

Researchers at the UCLA Samueli School of Engineering, in collaboration with the Optical Systems Division at Broadcom Inc., reported a broadband, polarization-insensitive unidirectional imager that ...

Though still only in the prototype stage, this flat lens could one day be used on space telescopes, and perhaps even on amateur telescopes. When you purchase through links on our site, we may earn an ...

For decades, imaging weakly scattering phase objects, such as cells, has been an active area of research across various fields, including biomedical sciences. One common approach uses chemical stains ...

Astronomers have discovered more than 5,000 planets outside of the solar system to date. The grand question is whether any of these planets are home to life. To find the answer, astronomers will ...

Please provide your email address to receive an email when new articles are posted on . Twelve years ago at the AECOS meeting, a program chair asked the audience if in 10 years we would be able to ...

The schematic of the presented QPI diffractive network, which reveals the quantitative phase information of an object behind a random unknown diffuser without the need for a digital image ...
