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 ...

Researchers detail how they used a type of 3D printing known as two-photon lithography to create lenses that combine refractive and diffractive surfaces. In a new study, researchers have shown that 3D ...

Miniaturized endoscopes with micron resolution, sub-millimeter diameters and 3D imaging capabilities play an important role in medical imaging and diagnostics. Common flexible endoscopes are based on ...

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 ...

Researchers propose a new method for achieving subwavelength resolution imaging for phase and amplitude objects. Their technique relies on diffractive encoding and decoding with a solid-immersion ...

We experimentally demonstrate imaging in the long-wave infrared (LWIR) spectral band (8 μm to 12 μm) using a single polymer flat lens based upon multilevel diffractive optics. The device thickness is ...
