sergepolar) потому, что когда только начинал приобщаться к науке на старших курсах, заходила речь о проблеме гамма-телескопа и как можно резко улучшить угловое разрешение с помощью наших эффектов. Но, похоже, не срослось...Telescope Concepts in Gamma-Ray Astronomy: https://arxiv.org/abs/2207.02248
Thomas Siegert, Deirdre Horan, Gottfried Kanbach
This chapter outlines the general principles for the detection and characterisation of high-energy γ-ray photons in the energy range from MeV to GeV. Applications of these fundamental photon-matter interaction processes to the construction of instruments for γ-ray astronomy are described, including a short review of past and present realisations of telescopes. The constraints encountered in operating telescopes on high-altitude balloon and satellite platforms are described in the context of the strong instrumental background from cosmic rays as well as astrophysical sources. The basic telescope concepts start from the general collimator aperture in the MeV range over its improvements through coded-mask and Compton telescopes, to pair production telescopes in the GeV range. Other apertures as well as understanding the measurement principles of γ-ray astrophysics from simulations to calibrations are also provided.

X-Ray Optics for Astrophysics: a historical review: https://arxiv.org/abs/2207.00512
Finn E. Christensen, Brian D. Ramsey
Grazing-incidence X-ray optics have revolutionized X-ray astrophysics. The ability to concentrate flux to a tiny detection region provides a dramatic reduction in background and a consequent very large improvement in sensitivity. The X-ray optics also permit use of small-format, high-performance focal plane detectors and, of course, especially for high-angular-resolution optics, provide a wealth of imaging data from extended sources. This review, follows the use of X-ray optics from the first rocket-borne instruments in the 1960s through to the Observatories flying today and being developed for future use. It also includes a brief overview of the challenges of fabricating X-ray optics and the various technologies that have been used to date
