“…The name for LE telescopes originates from the lobster whose eyes are made of small, reflective narrow channels [3]. Based on this design, Angel's arrangement was proposed [22] consisting of narrow square channels with reflecting surfaces leading to more compact x-ray optics.…”

Collimation of X-rays is challenging, especially for a wide range of grazing-incidence angles. One of the promising X-ray optics can be a wide-field Lobster-Eye optics in Schmidt's arrangement, which raised interest in recent years, and will be considered for simulations and description and is perspective for space missions.This paper introduces a newly developed simulator, PyXLA, written in Python and which evaluates and simulates specific types of X-ray reflective optics, particularly Lobster-Eye optics. The software utilises fundamental ray-tracing principles and, in combination with design, can determine the particular design's behaviour. The design relies on the mirrors' arrangements, surface finishing and reflectivity, and the X-ray detector, which catches the rays. This paper describes the newly developed PyXLA software, showing simulator principles and examples of outputs with a discussion of the applicability of results and other future extensions.

“…Currently, commonly used xray optics are Wolter types, mainly Wolter I, which has very high spatial resolution but a narrow FOV [2]. On the other hand, Lobster-Eye (LE) optics are another type of x-ray telescope that can theoretically achieve a FOV up to 360 • wide [3,4].…”

“…A number of mesopelagic teleost fishes have evolved unique eyes that benefit from both sources of light (through a combination of reflective and refractive optics) (Figure 3A), with the two moststudied species being the brownsnout spookfish (Dolichopteryx longipes) and the glasshead barreleye fish (Rhynchohyalus natalensis) [224][225][226][227] . The reflective eyes of decapods like lobsters spurred advances in the field of astrophysics, namely the development of "lobster-eye" Xray telescopes 228,229 , and the biomimetic design potential of further telescope innovations focused on the unique tilting of mirror plates in D. longipes eyes has been suggested 230,231 . A recent study created advanced models to test the optical performance of D. longipes, paving the way to the development of optical systems that can function in harsh environments including the deep sea 232 .…”

A forgotten element of the blue economy: marine biomimetics and inspiration from the deep sea

et al. 2022

The morphology, physiology and behavior of marine organisms have been a valuable source of inspiration for solving conceptual and design problems. Here, we introduce this rich and rapidly expanding field of marine biomimetics, and identify it as a poorly articulated and often overlooked element of the ocean economy associated with substantial monetary benefits. We showcase innovations across seven broad categories of marine biomimetic design (adhesion, antifouling, armor, buoyancy, movement, sensory, stealth), and use this framing as context for a closer consideration of the increasingly frequent focus on deep-sea life as an inspiration for biomimetic design. We contend that marine biomimetics is not only a “forgotten” sector of the ocean economy, but has the potential to drive appreciation of non-monetary values, conservation and stewardship, making it well-aligned with notions of a sustainable blue economy. We note, however, that the highest ambitions for a blue economy are that it not only drives sustainability, but also greater equity and inclusivity, and conclude by articulating challenges and considerations for bringing marine biomimetics onto this trajectory.

Modular coherent photonic-aided payload receiver for communications satellites

et al. 2019

Ubiquitous satellite communications are in a leading position for bridging the digital divide. Fulfilling such a mission will require satellite services on par with fibre services, both in bandwidth and cost. Achieving such a performance requires a new generation of communications payloads powered by large-scale processors, enabling a dynamic allocation of hundreds of beams with a total capacity beyond 1 Tbit s −1 . The fact that the scale of the processor is proportional to the wavelength of its signals has made photonics a key technology for its implementation. However, one last challenge hinders the introduction of photonics: while large-scale processors demand a modular implementation, coherency among signals must be preserved using simple methods. Here, we demonstrate a coherent photonic-aided receiver meeting such demands. This work shows that a modular and coherent photonic-aided payload is feasible, making way to an extensive introduction of photonics in next generation communications satellites.
