Photometric calibrations of an MCP space qualified photographic-camera
Abstract
The authors describe the methods developed to guarantee quantitative calibrations of a high sensitivity micro-channel plate photo-camera designed to obtain large scale night sky pictures of astronomical and geophysical interest in the optical and near infrared spectral range. In-flight calibrations were obtained with a sensitometer and absolute calibrations were performed in laboratory with a quasi-monochromatic black body source. Results obtained for calibrating the camera are given with emphasis on the comparison of measurements deduced in ground based and orbital condition.
