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.

The main feature of the compound diffractive telescope is the combination of diffractive optics with compound structure arranged eyepieces. In this paper
a design of the compound diffractive telescope is firstly introduced
and a 4.2 FOV is obtained with one primary lens and twenty-one eyepieces. Secondly
image characteristic of different channels is analyzed with the design wavelength in ASAP
and one modified phase function model of diffractive optical element is introduced to analyze the MTF curves for 0 FOV
which provides a more accurate prediction of the performance of the system. Then the system is tested by the star image test
and the diffraction limit images are got within 2 FOV. And finally
two pictures taken from the adjacent FOV proved to be able to be spliced together. All the results above demonstrate that a good performance of the compound diffractive telescope. 2009 SPIE.
