Solar EUV band has a very important meaning of detecting the physical processes and its controlling factors of solar
surface, and the Earth's environment as well as changes in the Earth's climate.
In the thesis we introduce the basic design of the solar ultraviolet telescope and imaging system .Because of small-band
transmission of the vacuum ultraviolet optical prism, we take double-Cassegrain reflector optical system. The sunlight
could be gathered to CCD detection system in order to image the sun in three specific spectrums involving 30.4nm,
58.4nm and 121.6nm. The reason we choose the center wavelength of 30.4 nm. 58.4nm and 121.6nm is that these three
spectrums contain a lot of bright lines, have a great radiation flux and play a significant role in ionizing and heating the
Earth's upper atmosphere.
We make UV telescope imaging system and ultraviolet light as a whole, then pump the whole system into vacuum to
simulate space environment. We introduce the calibration device in our system innovatively. Our thesis gives a detailed
description of the way of simulation of optical design, the vacuum system design and system calibration. Owing that our
system have the characteristic of Lightness, simple structure, small power, it is rather fit for astronomical observations on
the moon. The imaging results could provide very important research data for the middle and upper atmospheric
composition and ionospheric electron changes in density and communications research.
