In order to get enough information about the target
avoid big chromatic aberration as a result of wide spectrum and the complexity of optical system and adapt different special environment temperature
a hybrid refractive/harmonic diffractive optical system in far-infrared multi-band is described in the paper. This diffractive optical system has been designed an athermalized multi-band imaging system with harmonic diffractive element in 15-50m spectrum
based on larger 1dispersion capability and particular thermal dispersive power of harmonic diffractive element. Then
at the temperature range from 0C to 40C
this design can simultaneously meet with all requirements of the imaging system in five harmonic wave bands
including15.8-16.2m
18.5-20m
23-25m
30.5-33.5m and 46-50m. In each harmonic wave band
the magnification changes as a function of wavelength
which creates image registration error. To compensate this shortcoming
a zoom optical system is designed with three lenses by means of optical two- component method. The design results show that the hybrid refractive/harmonic diffractive optical system can realize athermalized and achromatic design
and the zoom optical system makes half image height at 3.53mm in every harmonic wave band and still realizes aberration compensation action. In the five harmonic wave bands
each optical transfer function approaches the diffraction limit at ambient temperature range of 0C to 40C. Finally
the system realizes the requirements of portability
mini-type and ease for fabrication. 2009 SPIE.

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.
