Deconvolution of an extended object viewed by a lobster-eye telescope

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

“…Fabricating such long, narrow, and smooth channels has proven problematic. Lens prototypes have been created using microchannel plate technology (MCP) [8,9,11,12] and etched silicon [13]. However, these lenses are extremely limited in their spectral range because of material [11,13].…”

“…Furthermore, MCP is produced as flat plates, requiring additional processing to create the needed curvature, which degrades the imaging quality of the lens [11,14]. Though there have been suggestions for electroplating glass MCP with nickel [12] and attempts at using lithographical techniques with metals to construct lobster-eye lenses [15,16], no technique has yet demonstrated the ability to produce a metal-surface lobster-eye optic with the required α.…”

Microscopic measurement using digital image restoration

“…However, in the imaging, transmission and storage process, the diffraction of an optical system, sensor of the nonlinear characteristics and other factors will cause the image degradation [1][2][3][4][5][6]. So that, great attention has been paid to restoring digital images, which is vital to improving the precision of micro-measure.…”

Microfabrication of massive parallel micromirror-lenses by X-ray LIGA technique: recent advances and prospects

“…In general, such lens systems rely on the warping of microchannel plates (MCP) and much work was done on classically bend MCPs for X-ray astronomy by Gorenstein (1993), Gorenstein et al (1996), Hudec et al (1999), Zhang (1998, 1999), , Priedhorsky and Christensen (1995), Priedhorsky et al (1996Priedhorsky et al ( , 1997, or for X-ray imaging in general by Lees et al (1997), Willingdale et al (1998), and Willingdale (1999). Estimations of image formation were carried out by Peele and Nugent (1998), Kupka et al (1998Kupka et al ( , 2000 and Peele (2001). Such lens-systems work also for the focussing of neutrons, as shown by Allman et al (1998) and Cimmino et al (1998).…”

“…However, best high aspect ratio technology enables to gain access to more advanced designs of MCPs, transgressing most of their disadvantages. First attempts to fabricate extended, warped MCPs by lithography and microtechnology was presented concerning the X-ray LIGA technique by Kupka et al (1998Kupka et al ( , 2000 and Peele et al (2001), and by for silicon MEMS technology. Other, refractive-based LIGA lenses are also possible to fabricate by LIGA (Kupka et al 1999).…”
