The coaxial two-mirror telescope consists of two mirrors facing each other. Classical two-mirror arrangements are Gregorian and Cassegrain. These systems are usually applied to space telescopes and often have optical baffles to prevent stray light from entering the focal plane. The optical baffles consist of concentric rings suspended between the secondary and the primary mirror. The secondary baffle for a large two-mirror optical system is designed and analyzed in this paper. According to mission of a telescope  the structure should have high stiffness and high reliability and light weight. Compared with invar  aluminum alloy and titanium alloy  carbon fiber composite is currently the best material in terms of weight-to-strength ratio. It also has advantages of high temperature tolerance and low thermal expansion. So carbon fiber composite is chosen as material to meet requirements of the coaxial telescope. In this paper  optimization method based on finite element analysis (FEA) is used for design the secondary baffle. Minimum weight of the baffle is chosen as an objective function. Thicknesses of former tube and vanes are chosen as variables. Analysis results show that the designed secondary baffle has maximum diameter of 180mm  total length of 120mm and weighs 142g. And its fundamental frequency reaches 651Hz. Therefore the baffle has many advantages  such as ultra-light weight  high stiffness and dimensional stability  etc. The optimization method and the baffle design can be helpful to other coaxial telescopes  such as Cassegrain  Gregorian and their subdivisions. 2012 IEEE.

Three-linear array tridimensional mapping camera consists of three independent linear CCD cameras. Unique position must be kept among the three linear CCD cameras. Optical lens is one of pivotal parts  MTF  the ground resolution power is 5m  resolving power  the distortion is 3/10000. They meet the need of user. 2009 SPIE.  distortion are its important techno-items. The optical lens of space tridimensional mapping camera is the key to accomplish the tridimensional mapping mission. In order to meet the need of user  a design on optical lens of transmission semi-telecentric beam path in image space is expounded  and assembly method based on DFT(Design For Test) of single lens suit and whole optical lens are expounded. The test results indicates that the MTF of optical lens referred in the paper is 0.45(@77lp/mm)
