Abstract

Thermal environment adaptability is an important aspect which should be involved in the development and test of a space camera. Generally, vacuum thermal test and thermal cycle test are two important thermal tests to ensure the reliability of a space camera. In this paper, vacuum thermal test and thermal cycle test of a space camera are introduced. During the test, we check if the camera can work normally and evaluate performance of the camera under different temperature. The performance is evaluated by the modulation transfer function (MTF) of the camera. According to the measured MTF curve, the influence of temperature on performance of this camera is evaluated.
