A classical X-ray optics of Wolter type has the FOV of only 1 deg or less. Lobster-eye optics was first proposed for astronomy as an X-ray telescope in the 1970s and the use of MPO device in a lobster eye X-ray telescope was reported by several investigators.

The lobster eye essentially an array of tube-like channels with a square cross-section was proposed as the basis of an X-ray all-sky monitor by Roger Angel of the University of Arizona in 1977.

Lobster eye x-ray telescope. Inspired by a lobsters vision the crustaceans pea-sized eyes give it wide-angle vision it is called the lobster-eye X-ray telescope. Its unique focusing ability within a wide field of view FOV in the area of X-ray detection had aroused widespread interests 10 11 12. A technique that allows soft x-rays to be focused using reflective elements that mimic a lobsters eye is extended to hard x-rays.

We give here a summary of the optical principle and discuss possible applications. Lobster Telescope has an Eye for X-Rays. The LE optics are based on a real analogy with the lobster eyes.

UK astronomers have been at the forefront of designing a revolutionary new X-ray telescope that is based on the eyes of a lobster. This ray-traced simulation shows the Lobster instrument as it would appear on the Columbus module of. Lobster eyes as X-ray telescopes.

Two basic types of Lobster Eye Wide Field Xray tele- scopes have been proposed for astrophysical applications. The Lobster-Eye LE X-ray telescope can be miniaturized for an application in picosatellites. By replicating the crustaceans ability to observe.

Lobsters see by reflection not refraction. Using lobster-eye optics in hard-x-ray imaging systems. This is solved by a device like the Lobster Eye telescopebut running in reverse as it were see diagram X-rays are produced by a laser zapping a small point of metal and heating it to about 1 million C almost 2 million Fthis spot is strategically located at the focus of the lobster eye and a parallel beam emerges from the eye.

The Lobster Eye telescope will look for soft X-rays in the energy range 01 to 35 kiloelectronvolts. Results of analyses and simulations of lobster-eye X-ray telescopes have indicated that they would be able to monitor the X-ray sky at an unprecedented level of sensitivity an order of magnitude better than any previous X-ray all-sky monitor. Its eyes are a microchannel plate a thin curved slab of material dotted with tiny tubes across the surface.

X-ray light enters these tubes from multiple angles and is focused through grazing-incident reflection giving the technology a wide field of view necessary for finding and then imaging transient events that cannot be predicted in advance. These are mostly produced by a few hundred X-ray. X-ray telescope borrows lobster-eye technique.

By their nature x-rays are difficult to focus refractively. A detailed description of x-ray telescopes based on the optical principles of lobster eyes is to be published elsewhere shortly Angel 1979. The LE tele-scopes are novel wide ﬁeld X-ray telescopes with the ﬁeld of view FOV of typically 100 sq.

UK astronomers have been at the forefront of designing a revolutionary new X-ray telescope that is based on the eyes of a lobster. In collaboration with NASA Los Alamos National Laboratory Los Alamos NM and Leicester University Leicester. The lobster X-ray instruments optics would work the same way.

The lobster-eye LE geometry X-ray optics offer an excellent opportunity to achieve very wide fields of view 1 000 square degrees and more while the widely used classical Wolter grazing incidence mirrors are limited to roughly 1 deg FOV. Michael Gertsenshteyn Gajendra Savant and Tomasz Jannson. Our approach is based upon the geometry of Schmidt 1975 in which a telescope is composed of two similar orthogonal stacks each made from equally spaced identical flats that reflect on both faces.

Wide field x-ray telescopes based upon the lobster eye geometry can play an important role in future astronomical investigations. However it has taken almost 30 years and nearly 15 years from the first successful X-ray measurements with such structures in 1992. Composed entirely of straight walls and right angles as opposed to the human eyes curved rods and cones a lobsters eye reflects the light beams that enter at standard very shallow.

At the University of Melbourne Melbourne Australia researchers are developing a prototype imaging x-ray telescope based on the biological construction of a lobster retina. The reflection is made possible by thousands of squares located in the lobsters eyes which are near the base of the antennaeThese squares are the lobsters optics. A new optical configuration for grazing-incidence imaging X-ray telescopes is described that is similar to the reflective.

Lobster telescope has an eye for X-rays. Angel Arizona Steward Observatory University Steward Observatory University of Arizona 85721 Tucson Arizona 85721 Tucson of x-ray telescopes based on the optical principles A detailed description of x -ray telescopes based on the optical principles of lobster here a summary of the elsewhere shortly Angel. By replicating the crustaceans ability to observe objects all around it without turning its head scientists are confident that the Lobster instrument will enable a major.

The Lobster eye design for a grazing incidence X-ray optics provides wide field of view of the order of many degrees for this reason. Lobster Eyes As X-Ray Telescopes Angel J. By mimicking the way lobsters eyes work scientists have designed new X-ray space telescopes that can survey much larger areas.

A new optical configuration for grazing-incidence imaging X-ray telescopes is described that is similar to the reflective eyes of macruran crustaceans such as lobsters. The telescopes in Schmidt arrangements are based on. Lobster Eye Xray Telescopes The LobsterEye LE telescopes are based on grazing incidence optics analogous to those in eyes of lobsters and crayfish Figs.
