Global warming has become a very serious issue for human beings. The substantial increase of column carbon dioxide (CO2) results in temperature raised of the earth’s surface. One important specification is that it must have an ultra-spectral ability to measure concentration inversion of CO2, developing ultra-spectral remote sensors is an significant direction. This paper brings a new spectrometer on atmospheric sounding, that splits spectrum with a new type of narrow-band interference filter. It can simultaneity get super finely spectrum, compact configuration, and easy to achieve. That has broad applied foreground.
A new kind of polarization modulation is presented in this paper-sinusoidal polarization modulation. It can acquire the
full linear polarization information of targets. The large advantage of this modulation is that it is very compact and with
low mass and there is no moving parts in it. Moreover the demodulation algorithm is not only simple but also with high
precision. It’s especially suitable for spaceborne atmosphere detecting sensor, providing a new kind of polarization
modulation for it. After the incident lights passing through the modulator, it is modulated into sinusoidal with amplitude
scaling with the degree of linear polarization and phase scaling with the angle of linear polarization. With a dedicated
algorithm, the degree and angle of linear polarization can be acquired directly while traditional polarization modulation
methods need I、Q、U、V parameters of the Stokes vector for further calculation. In this paper, theoretical and simulation
analysis on spectral modulation are presented, the results of analysis point out the feasibility of this technology in theory.
Climate warming has become a serious problem facing all countries in the world, the impact of global climate change on
the human environment subject to widespread international concern. In recent years, American and European countries
invest a lot of manpower and resources to carry out the detection load of Atmospheric and Environmental Research, and
the ultra-high spectral resolution capability is an important prerequisite for the realization of atmospheric trace
constituents exact retrieved, the development of ultra-high spectral resolution load has become an important trend. This
paper presents a new compact spectrometer for atmospheric and environmental exploration, which uses a narrow-band
interference filter type, filter through different angles of incidence of the light beam spectral drift characteristics , to
achieve ultra- fine spectral splitting . This spectrometer while achieving ultra-high spectral resolution , the structure of a
compact camera with good engineering can be realized , and has broad application prospects.
Polarization hyperspectral imagers combine polarization technology, spectral technology and imaging technology, get both the image of the target and the polarization and spectrum of the pixel to recognize the materials on the objects，have broad applied foreground on airborne remote sensing domain. That arrests extensive attention abroad.
This paper brings hyperspectral technology and polarization image together. On the basis of geometrical optics theory
and polarization theory, puts forward a new polarization hyper-spectral Imaging technology. That could get hyper-spectral information and whole Stokes elements spectral from the object on the measuring the power spectral from
the modulator only one time, and that raise the ability of recognization greatly. The paper carries out a project to the new airborne polarization hyperspectral imager.
