Fresnel zone plate (FZP) stacking is an approach to enhance diffraction efficiency in x-ray focusing and imaging by physically aligning 2 or more FZPs to increase the effective thickness and optical ...

Optical aberration theory remains a fundamental component in the design and operation of space telescopes. With increasingly ambitious astronomical missions and the demand for high-resolution imaging, ...

Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

The Apollo program is a constant reminder that we just don’t need so much to get the job done. Sure it’s easier with today’s tools, but hard work can do it too. [Bill Hammack] elaborates on one such ...

New multicore optical fibers have many times the signal-carrying capacity of traditional single-core fibers, but their use in telecommunications has been severely restricted because of the challenge ...

Photonex + Vacuum Technologies 2021 provides the photonics industry in the UK with an excellent platform to present the latest research results and practical examples from industry. Aerotech is ...

Evenly spaced: illustration of the optical spectrum of a frequency comb. (Courtesy: J Wang/NIST) A new technique that could vastly improve the accuracy of the time and distance measurements made using ...

PI (Physik Instrumente) offers a new 6-axis variant of its successful F-141 PINovAlign automated fiber alignment system.
