| Abstract: | Aiming at the deviation of multi-optical axis parallelism because of the temperature and humidity in field,an optical system is designed for measuring the multi-optical axis parallelism among visible light,1.06μm laser and 8~12μm long wave infrared.The optical system takes Cassegrain system as co-window and visible light as the reference axis.On the basis of the initial structure parameters and optimization,the primary and secondary mirror of Cassegrain system are hyperboloid which can correct spherical aberration and coma,and the addition of the correction mirror can decrease external axis aberration.The experiment shows that the image quality reaches the diffraction limit and optical properties meet requirements which play a key role in the measurement of multi-optical axis parallelism in field. |
