Dragonfly eyes inspire new microlens array processing technique

Industry 4.0 requires simple solutions for complex functions. Optical sensors, such as pinhole cameras, can deliver a depth of focus and reasonable resolution, but they suffer from low intensity for reliable and fast imaging. ...

On-chip generation of Bessel-Gaussian beam for long-range sensing

The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied in widespread applications, including quantum entanglement, underwater 3D imaging, optical micro-manipulation, microscope, ...

Orbital angular momentum boosts multiplexed holography

Optical holography is a powerful method for recording and reconstructing complete optical field information, including intensity and phase. It has found extensive applications in various fields, such as optical display, imaging, ...

Video: Hera Propulsion Module leak test, in time-lapse

ESA's Hera mission for planetary defense will perform a close-up survey of the Dimorphos asteroid in deep space. But first Hera needs to cross millions of kilometers of space to get there. That is the task of Hera's Propulsion ...
