Curved FPAs at Last?

Two members of the European Astronomical Society (EAS) have been awarded prizes this week during the European Week of Astronomy and Space Science (EWASS2017) in Prague, Czech Republic, in part to acknowledge their involvement in the emergence of curved detectors: The Tycho Brahe Prize for Bernard Delabre from the European Southern Observatory (ESO), and the New Technologies MERAC prize for Emmanuel Hugot from the Laboratoire d’Astrophysique de Marseille, who is leading an ERC programme on these developments.

The small world of curved detectors, either CCD or CMOS-like, starts to be very competitive, preparing a tremendous revolution in the field of wide field imaging systems. By directly correcting the field curvature in the focal plane, curved detectors help saving about one third of the optics, usually used as field flatteners, and then avoids undesirable distortion effect either in the image and also on the optical properties across the field of view.
