Title: | Distortion definition and correction in off-axis systems | Authors: | Da Deppo, Vania SIMIONI, EMANUELE Naletto, Giampiero CREMONESE, Gabriele |
Issue Date: | 2015 | Volume: | Optical Systems Design 2015: Optical Design and Engineering VI | Editors: | Mazuray,Laurent; Wartmann, Rolf; Wood, Andrew P. | Series: | PROCEEDINGS OF SPIE | Number: | 9626 | First Page: | 962634 | Abstract: | Off-axis optical configurations are becoming more and more used in a variety of applications, in particular they are the most preferred solution for cameras devoted to Solar System planets and small bodies (i.e. asteroids and comets) study. Off-axis designs, being devoid of central obstruction, are able to guarantee better PSF and MTF performance, and thus higher contrast imaging capabilities with respect to classical on-axis designs. In particular they are suitable for observing extended targets with intrinsic low contrast features, or scenes where a high dynamical signal range is present. Classical distortion theory is able to well describe the performance of the on-axis systems, but it has to be adapted for the off-axis case. A proper way to deal with off-axis distortion definition is thus needed together with dedicated techniques to accurately measure and hence remove the distortion effects present in the acquired images. In this paper, a review of the distortion definition for off-axis systems will be given. In particular the method adopted by the authors to deal with the distortion related issues (definition, measure, removal) in some off-axis instruments will be described in detail. <P /> | Conference Name: | SPIE OPTICAL SYSTEMS DESIGN | Conference Place: | Jena/ Germany | Conference Date: | 7-10 September 2015 | URI: | http://hdl.handle.net/20.500.12386/23085 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9626/1/Distortion-definition-and-correction-in-off-axis-systems/10.1117/12.2191332.full?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781628418156 | DOI: | 10.1117/12.2191332 | Bibcode ADS: | 2015SPIE.9626E..34D | Fulltext: | open |
