Lobster Eye X-ray Optics

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. A classical X-ray optics of Wolter type has the FOV of only 1 deg or less.

In contrast to existing scanning pencil beam systems Lobster Eye X-Ray Imaging Systems true focusing X-ray optics simultaneously acquire ballistic Compton backscattering photons CBPs from an entire scene irradiated by a wide-open cone beam from one or more X-ray generators.

Lobster eye x-ray optics. The device consists of a set of flat reflecting surfaces. Scopes are novel wide field X-ray telescopes with the field of view FOV of typically 100 sq. 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 angles or grazing angles.

The wide-field X-ray Lobster-eye opticscollimator depending on energy is used with a view angle of 3 degrees for the source location definition. We proposed to develop and manufacture the Wide-Field Lobster-Eye X-ray Optic by mean of a special electroforming and replication process. Using lobster-eye optics in hard-x-ray imaging systems.

Its eyes are a microchannel plate a thin curved slab of material dotted with tiny tubes across the surface. The lobster-eye geometry X-ray optics offers an excellent opportunity to achieve very wide fields of view. Michael Gertsenshteyn Gajendra Savant and Tomasz Jannson.

We review the design and basic properties of the wide-field x-ray optical system based on one- and two-dimensional lobster-eye geometry and suggest technologies for their development and construction. We review the design and basic properties of the wide-field x-ray optical system based on one- and two-dimensional lobster-eye geometry and suggest technologies for their development and construction. 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.

Lobster eye optics as a wide field of view imaging system is perfectly suited for x-ray astronomy but can be useful also in the lab. Lobster eye optics are a radical departure from current missions designed for large-area modestresolution optics include the Broad Band X-Ray Telescope recently flown as part ofthe Astro mission on the space shuttle the Soviet Spectrum-X-Gamma mission the Italian X-ray astronomy satellite SAX the Japanese X-ray spectroscopy satellite Astro-D and the European conventional X-ray. Lobster-Eye optics refers to an optical element used to focus soft X-rays developed by the University of Leicester in the UK.

Luning Su Wei Li Mingxuan Wu Yun Su Chongling Guo Ningjuan Ruan Bingxin Yang and Feng Yan. Lobster eyes as X-ray telescopes. A rapid evaluation of the image distribution.

Modeling the focusing efficiency of lobster-eye optics for image shifting depending on the soft x-ray wavelength. The Lobster Eye X-ray Imaging System collects focuses thousands of times more backscattered hard X-rays in the range. The alternative x-ray optics geometries achieving very large fields of view have been theoretically suggested in the 70s but have been not constructed and used so far.

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. Lobster eye optics will enable us to construct X-ray telescopes capable of simultaneously viewing a large fraction of the sky making possible a new class of X-ray astronomy survey and monitoring missions. 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.

Wide field X ray optics of the Lobster-Eye type as well as related optical and X-ray test methodology. The optical element consists of an array of very small square glass pores 20 microns on a side curved like a section of a. We describe a novel system for focusing X-rays based on the eye of a lobster and a method for fabricating such optics using microchannel plates which have pores with square cross sections.

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 it can be a convenient approach for the construction of space all-sky X-ray monitors. Wide field X-ray monitors of Lobster Eye type were demonstrated to play an important role. 5622 6267-6271 2017 Lobster-eye x.

Lobster-eye optics is widely applied to space x-ray detection missions and x-ray security checks for its wide field of view and low weight. The LE optics are based on a real analogy with the lobster eyes. In contrast to existing scanning pencil beam systems Lobster Eye X-Ray Imaging Systems.

The alternative x-ray optics geometries achieving very large fields of view have been theoretically suggested in the 70s but have been not constructed and used so far. 37 4 632-642 1998 Numerical model built for the simulation of the earth magnetopause by lobster-eye-type soft X-ray imager onboard SMILE satellite. A technique that allows soft x-rays to be focused using reflective elements that mimic a lobsters eye is extended to hard x-rays.

In France and inspired by the eyes of the eponymous epicurean crustacean. One-dimensional lobster-eye geometry was originally suggested by Schmidt Schmidt 1975 based upon flat reflectors. The lobster X-ray instruments optics would work the same way.

The inner surface of optically precise. A Lobster Eye X-ray Imaging System based on a unique Lobster Eye LE structure X-ray generator scintillator-based detector and cooled CCD or Intensified CCD for real-time safe staring Compton backscatter X-ray detection of objects hidden under ground in containers behind walls bulkheads etc. This paper presents a brief overview of the technologies developed in our group where the glass and silicon mirrors are used to built up the Schmidt lobster eye design and mainly discuss the mirror design consequences on the resulting imaging properties of the.

The X-ray mirror of this type Angel type consist of a large number square channels aligned on the surface of the sphere. By their nature x-rays are difficult to focus refractively. These squares are the lobsters optics.
