Unlike a reflective solar sail, a sun-facing diffractive solar sail uses a component of force perpendicular to the sun line. This allows navigation without sacrificing the amount of solar power on the ...

A paper by CU Boulder Professor Rafael Piestun and PhD candidate Haiyan Wang on diffractive optics was recently published in Optica, the most prestigious journal published by The Optical Society of ...

Thanks to a set of unique properties, diffractive optical elements have the potential to transform light into almost any desired distribution. Joshika Akhil gives the low-down on the technology that ...

The Diffractive Solar Sailing Project, led by Amber Dubill of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, would enable spacecraft, like probes and satellites ...

Spatially incoherent diffractive optical processors can handle data beyond non-negative values, potentially making them valuable in diverse scenarios, such as visual encryption and autonomous ...

Today we are fortunate to have three FDA-approved diffractive IOL designs that provide a full range of uncorrected vision for our cataract surgery patients. With these new options, we anticipate a ...

While reflective solar sails have been discussed as a possibility for space travel for decades and the first spacecraft to use the technology launched in 2010, the project team believes that ...

A diffractive camera design performs class-specific imaging of target objects with instantaneous all-optical erasure of other classes of objects. This diffractive camera consists of transmissive ...

Following a one-time training on a computer, the resulting visual processor with its passive diffractive layers is fabricated, forming a physical image denoiser that scatters out the optical modes ...

Grating light valve (GLV) diffractive optical MEMs are an alternative approach. Basically, the GLV device is a spatial light modulator with applications in areas such as dynamic gain equalizers and ...
