Based on the design principles of Fourier lens system and the requirements of some particles observation experiment  a Fourier optical system whose working wavelength was 532nm was designed using ZEMAX. The testing experiment using the visual microscope  showed that the system's resolution was 250lp/mm. And the system was successfully used in the particles observation experiment. 2011 IEEE.   Design of optical lens for space tridimensional mapping camera (EI CONFERENCE) 会议论文 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Advanced Optical Manufacturing Technologies, November 19, 2008 - November 21, 2008, Chengdu, China Zhang L.-P.; Wang Z. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 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)   Design of the infrared dual-band athermalized optical system based on HDE (EI CONFERENCE) 会议论文 International Symposium on Photoelectronic Detection and Imaging 2009: Advances in Infrared Imaging and Applications, June 17, 2009 - June 19, 2009, Beijing, China Dong K.; Zhang L.; Wang J.; Wang H.; Sun Q.; Lu Z. 收藏  |  浏览/下载：87/0  |  提交时间：2013/03/25 A dual-band infrared optical system adopting an uncooled LW infrared detector and a cooled MW infrared detector is designed and manufactured  while in the LW IR band the F/# is 1 and the focal length is 114 mm  based on the athermal ability and special diffractive properties of harmonic diffractive elements. The design shows in the MW IR band the F/# is 2 and the focal length is 72 mm  for the temperature range -40 70 the MTF value is over 0.5 at 10 lp/mm. Finite element method is applied to the opto-mechanic structure of the system for thermal analysis  for the temperature range -40C 70C the MTF value is over 0.4 at 20 lp/mm  which confirms the imaging ability of the system in a wide temperature range. 2009 SPIE.   A spherical catadioptric telescope system based on Cooke corrector group (EI CONFERENCE) 会议论文 Novel Optical Systems Design and Optimization XII, August 3, 2009 - August 4, 2009, San Diego, CA, United states Zhang J.; Kang Y.; Liu W. 收藏  |  浏览/下载：26/0  |  提交时间：2013/03/25 To obtain a number of advantages in fabrication  testing and alignment  many designs in which spherical mirrors replace classical Cassegrain-form aspheric mirrors are present in the literature. However  spherical mirrors suffer from substantial spherical aberration and thereby require some form of corrector group. But in this case  the question encountered is that of making the basic optical configuration more complex. In this paper  a new design based on Cooke corrector group is presented for eliminating spherical aberration  which is believed to provide higher performance with less complexity than previous approaches. Besides  the cost and fabrication period will be extremely decreased. The telescope system using corrector group here can achieve good optical performance with f# of 10  full field of 0.5  obscuration of 1/3 and MTF (Modulation Transfer Function) of 0.48 corresponding to 50@lp/mm. 2009 Copyright SPIE - The International Society for Optical Engineering.
