可实现激光发射并保证激光的准直性。

Abstract

On the structure characteristics of emission telescopes

this paper designs and assembles a 270 mm Mersenne reflecting afocal Cassegrain transmitter-telescope to achieve the laser emission and laser collimation. Firstly

the design method for an on-axis reflected system was determined and its system parameters were given. Based on the finite element method

the deformations of cylinder and truss primary mirror supporting structures and that of the three-beam and four-beam secondary mirror support structures were analyzed in the different working conditions

and the three-beam secondary mirror support structure and the truss structure were chosen to be used in the telescope. Furthermore

systematic optical aberration caused by the secondary mirror decentration was analyzed by adjusting primary and secondary mirror structures with the help of an interferometer and an autocollimation plane mirror and a sensitivity matrix was obtained to assembly

adjust and test the system. Finally

obtained results show that the systematic wavefront aberration RMS and PV are 0.146 7λ

and 0.739 41λ respectively. It is proved that the design of the transmitter-telescope has a better imaging quality and satisfies the requirements of the optical design and laser emission.
