Performance Of A Digicon Photon-Counting Autoguider System

The operation and performance of a Digicon-based autoguider system recently developed will be discussed. The photosensor is a twelve-channel, photon-counting Digicon specifically developed by SAI for this application. The design and implementation of the system will be discussed with an emphasis on the objective of developing a general purpose auto-guider system for a wide range of applications. Data will be presented on the Digicon performance, i.e., quantum efficiency, background count rate, and pulse counting performance. In addition, overall system guiding accuracy, dynamic range, and sensitivity will be detailed.© (1984) COPYRIGHT SPIE--The International Society for Optical Engineering.
