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.

In this paper  we are presenting a design method and its results for a space optical system with high resolution and wide field of view. This optical system can be used both in infrared and visible configurations. The designing of this system is based on an on-axis three-mirror anastigmatic (TMA) system. Here the on-axis concept allows wide field of view (FOV) enabling a diversity of designs available for the Multi-Object Spectrometer instruments optimized for low scattered and low emissive light. The available FOVs are upto 1 in both spectrum ranges  whereas the available aperture range is F/15 - F/10. The final optical system is a three-mirror telescope with two on-axis and one off-axis segment and its resolution is 0.3m or even lower. The distinguished feature of this design is that it maintains diffraction-limited image at wide wavelengths. The technological developments in the field of computer generated shaping of large-sized optical surface details with diffraction-limited imagery have opened new avenues towards the designing techniques. Such techniques permit us to expand these technological opportunities to fabricate the aspherical off-axis mirrors for a complex configuration.

With the development of optical information processing  high-resolution Fourier transform lens has often been used in holographic data storage system  spatial filtering and observation of particles. This paper studies the optical design method of high-resolution Fourier transform optical lenses system  which could be used in particles observation and holographic data storage system. According to Fourier transform relation between object and its frequency plane and the theory of geometrical optics  the system with working wavelength 532nm and resolution 3 m was designed based on ZEMAX. A multi-configuration method was adopted to optimize the system's lenses. In the optical system  a diaphragm was placed at the system's spectrum plane and the system demanded a low vacuum to cut down the influences of atmosphere and other particles. The result of finite element analysis indicated that the influences of vacuum pumping to optics spacing and mirror surface shape very minor  and the imaging quality not being affected. This system has many advantages  such as simple structure  good image quality and a high resolution of 3 m. So it has a wide application prospect and can be used both in holographic data storage system and particles observation.

TMA (Three Mirror Anastigmatic) is popular to the design of space-based optical system. This paper describes the characteristics of the on-axis TMA optical system. An on-axis TMA system with 13m focal length is designed and analyzed. To solve the initial configuration parameters  Cassagrain structure is confirmed firstly  and then the tertiary mirror. Based on initial configuration parameters  automatic optimization is executed in ZEMAX program  and design result with excellent image quality is acquired  which shows the procedure we choosed with good advantage of computer processing. As the distortion of the design reaches 1%  its influences on TDICCD brushing camera are discussed. The source of distortion is analyzed and correcting methods are considered. Zero focal power corrector is chosen to correct the distortion  and the corrected distortion is less than 0.02%. The research on on-axis TMA system in this paper makes a foundation for farther high-resolution remote sensing applications.
