An optimum structure design for Cassegrain optical system

Because the energy loss caused by the secondary mirror of Cassegrain antenna is seriously, an optimum structure is designed to improve the transmitting energy of Cassegrain optical system. It is made up of Cassegrain antenna and Double pyramidal system. The parameter of Cassegrain antenna has been analyzed, and it has been revealed that relationship between the Double pyramidal system and Cassegrain antenna. Finally, the relationship between the optimum parameters of Cassegrain and the transmitting efficiency has been researched. Through this optimum structure, the emitting power can be achieved to 91.5%.
