O.C.A. Schmidt Telescope CCD Camera Controller.

摘要

This document describes a new COD camera controller adapted to Schmidt telescopes. If several large COD detectors can be adapted in the focal plane of a large Schmidt telescope, deeper digital images can be obtained, the operating cost of a COD camera is several orders of magnitudes smaller than that of glass photographic plates. This also opens new ways of using Schmidt telescopes; i.e., real time detection of celestial sources. This report contains the following sections: Requirements analysis Description of the Loral CCD442A CCD Description of the camera controller Physical implementation of a mono CCD camera Physical implementation of a multi CCD camera Appendix 1: Electronic schematics of the O.C.A. CCD camera controller Appendix 2: Data sheets of the main components of the O.C.A. controller Appendix 3: 87C750 based sequencer software.
