ELECTRON-BOMBARDED ACTIVE PIXEL SENSOR STAR CAMERA |
| 摘要 |
A star camera system that includes an optical system configured to focus radiation from a star to be imaged onto a collector. Specifically, the collector is in the form of an electron bombarded active pixel sensor (EBAPS) configured to provide high gain. The EBAPS comprising a photocathode disposed in a vacuum is configured to release electron into a vacuum when exposed to radiation focused thereon by the optical system. In addition, the EBAPS includes an active pixel sensor anode disposed distant from the photocathode in the vacuum. An electric field is generated by a voltage source to direct electrons from the photocathode to the active pixel sensor anode to thereby generate an image of the star. |

1. A star camera system, comprising:
an optical system configured to focus radiation from a star to be imaged onto a collector; and a collector in the form of an electron bombarded active pixel sensor configured to provide high gain, including:
a photocathode disposed in a vacuum and configured to release electrons into a vacuum when exposed to radiation focused thereon by the optical system;an active pixel sensor anode disposed distant from the photocathode in the vacuum; anda voltage source to generate an electric field configured to direct the electrons from the photocathode to the active pixel sensor anode to generate an image of the star. |
