Title: | Telecentric F-theta fisheye lens for space applications | Authors: | PERNECHELE, Claudio Consolaro, Luca Jones, Geraint H. Brydon, George Da Deppo, Vania |
Issue Date: | 2021 | Journal: | OSA CONTINUUM | Number: | 4 | Issue: | 3 | First Page: | 783 | Abstract: | A very wide angle lens with a field of view of 360°x180° - a fisheye lens - has been designed to be used in a space environment. As a case study, the lens is assumed to be mounted on a spinning probe passing through a comet’s tail. The lens, rotating with the probe passing through the comet coma, may map the entire sky as viewed from the interior tail, providing unprecedented data on the spatial distribution of plasma and dust. Considering the foreseen space applications for the lens, radiation hardened glass has been taken into account for the design. A key feature of the lens is the “angular scale” uniformity (F-theta) of the sky distribution map projected on the focal plane allowing to obtain a reliable whole sky reconstruction. Care has also been taken to obtain an almost telecentric design, in order to permit filters placed on the focal plane to work properly. A telecentric fisheye operating with a pixel-limited resolution in the waveband from 500 nm up to 770 nm and with an F-theta distortion is presented in this paper. | URI: | http://hdl.handle.net/20.500.12386/34388 | URL: | https://opg.optica.org/osac/fulltext.cfm?uri=osac-4-3-783&id=447843 https://api.elsevier.com/content/abstract/scopus_id/85109208982 |
