“…It has an important position in the United States space industry. Yang [6] designed a spatial dual-band infrared target simulation optical system by combining the methods of thermal loss and achromatic loss, the principle of which is mainly based on the complementarity of the focal length displacement coefficient between optical materials. Liu [7] developed ZM3000, a test equipment capable of simulating space environment, for the optical performance of the remote sensor in space environment and the stability of the whole system.…”
