Current research on space-based exploration for the ionosphere needs more advanced technologies. Because the spectral signals in the ionosphere distributing basically in the far-ultraviolet waveband are very weak. Usual spectrometer structures and detectors such as CCD can't receive enough information. Based on this principle of atmospheric sounding  the imaging spectrometer prototype for ionosphere detection application was designed to solve the problem. This prototype consists of the telescope and the imaging spectrometer. The simple structure and small number of mirrors can help higher transmission efficiency be achieved and weak signals detection be implemented. The telescope is an off-axis parabolic mirror and the spectrometer is a modified Czerny-Turner spectral imaging system. Modified Czerny-Turner spectrometer contains a spherical mirror  a fixed plane grating and a toroidal mirror. By adjusting the incident angle to the collimating mirror and using toroidal mirror  coma and astigmatism were corrected well. We also optimize distances between the grating to the focusing mirror and the focusing mirror to the image plane to improve disadvantages of traditional Czerny-Turner structure. Designed results demonstrate that aberrations are substantially corrected  and high image quality can be obtained in broad waveband. The photon counting Wedge-Strip-Anode detector with micro-channel planes as the receiving plane is accepted for the instrument prototype. The other photon counting 2-D detector responding well for weak light such as Cross-Delay line detector and MAMA detector can also be used for detection. The calibration and performances testing system is made of a vacuum system  a deuterium lamp  a monochrometer and the instrument prototype. Results obtained from the experiment show that the spectral resolution is 2.4 nm and the spatial resolution is 80 m. The other calibration experiments are running. The technology of the spectrometer prototype is important for the research and applications of ionosphere remote sensing. 2011 SPIE.

This paper describes a kind of automatic test technology of the parameters used in a dual-CCD TV measure-system (TV -MS) .The TV -MS is the ground control equipment of the anti-tank missile and integrates the technologies of optical  machine and electronics. It is important and key component. The main technical parameters of the TV -MS are field of view  zero point  precision  sensitivity  anti-jamming ability  zooming time and focus time  etc. To insure the TV -MS satisfying the tactical and technical requirements and discover fault and reason  a fast and accurate equipment satisfying the test technical parameters of the TV -MS is urgently needed in manufacture and service. Firstly  the parameter test system converted optical signal to electronic signal  implemented automatic control of the invariant illumination of parallel pipeline output. Secondly  data and command delivering  displaying or printing are realized by using 80C196KB. The experiment result shows that the approach of automatic testing of the Parameters used in a dual-CCD TV -MS is successful and it can be used for all tests of the functions and parameters of the TV -MS. The main innovations are to realize the fast  veracious measure of technical parameters of the dual-CCD TV-MS  and integrate the technologies of optics  machineries and electronics. An advanced means is provided to judge the technical states  find malfunctions and discover the reasons in producing and maintaining process. The equipment suited for anti-tank missile systems is given.
