| Abstract: | In this paper,the optical system design of the high-resolution visible spectral camera for China first Mars exploration mission is planned. Firstly,the scientific meaning and the development trend of the Mars high-resolution camera is proposed. And then,by analyzing the application advantages of various optical systems,the Off-axis Cook system is selected to apply for the China Mars high-resolution camera. Besides,the aspherical mirror testing plan is proposed. By using the optical system,the optical system can guarantee the high-resolution camera reach the international advanced level. |
