To obtain high resolution
high signal-to-noise ratio (SNR)
high reliability and real time in wide spectral range
we study the space modulation Micro Fourier Transform Spectrometer (FTS) based on multi-step mirrors covering the spectral range of 3-5m and 8-12 m in theory and experiment. The influences of spectrum reconstruction caused by the diffraction and extended light source in Fourier Transform Infrared Spectrometer (FTIR) are analyzed. A method to reduce the noises in spectrum reconstruction and the relationship between coherent intensity and solid angle of light source are discussed. An extended light source with suitable size is chosen
considering the requirement of SNR and spectrum resolving power in the optical design. Furthermore
the fabrication of micro multi-step mirrors
which is the core part of FTS
is investigated. Three methods for fabricating multi-step micro mirrors are demonstrated. 2011 IEEE.

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.

A novel Interleaver using a modified Michelson interferometer in which its reflecting mirrors are replaced by three-mirror Fabry-Perot interferometer and Gires-Tournois resonator respectively is presented. On basis of the theory of Michelson interference
a designing principle of the interleaver
which has square-like frequency response with zero ripple
wide flat-top
unity contrast
simple structure
and stable performance
is given. The device which possesses channel spacing of 50 GHz
zero ripple
0.5 dB bandwidth more than 0.27 nm
and close channel isolation more than 73 dB has been designed.
