Astronomical lobster eye telescopes

Comparison of focal properties of square-channel and meridional lobster-eye lenses

“…3(b)] is similar to that of the squarechannel lens, with detailed differences, which are studied here. The use of foils as the main construction element is advantageous because the technique for producing foils from metals is well known [2,17]. Furthermore, the design does not require the additional process of adding curvature [11,15].…”

“…The use of flat foil plates to create the channel walls has been proposed for manufacturing lobster-eye lenses as an alternative to producing square channels in a substrate [2,4,8,17,18]. To create the lobster-eye lens geometry, the plates are organized along two sets of orthogonal meridional lines (the crossmeridian geometry [14] or meridional lobster-eye lens) [8,14,17,18], as in Fig.…”

“…X-Ray Astronomy The x-ray sky is vibrant and variable, with astronomical sources such as black holes, stellar coronae, and supernovae emitting within the x-ray spectrum [1,2]. Deep-field x-ray telescopes have been deployed since the Einstein telescope launched in 1978 [3], and, though the angular resolution has improved, the field of view (FOV) remains limited to ≈1∕2°due to geometric constraints.…”

“…Deep-field x-ray telescopes have been deployed since the Einstein telescope launched in 1978 [3], and, though the angular resolution has improved, the field of view (FOV) remains limited to ≈1∕2°due to geometric constraints. Though no wide FOV x-ray imaging telescope currently exists [4], one would be extremely valuable as an all-sky monitor (ASM) for locating and identifying new galactic and extragalactic sources [2] and observing the evolution of transient sources [5].…”

Application of biomimetics principles in space optics

“…There is also potential for possible extending the wide field imaging system to higher energy by the use of multilayer or other coatings in analogy to those described for flat reflectors in the KirkpatrickBaez geometry. Experimental designs of LE X ay telescopes were reported many times over last years [17][18][19][20][21][22]. Miniature LE objectives were developed and tested allowing applications on nano and cubesatellites (Figs.…”
