According to the area CCD camera of characteristics
such as high resolution capacity and high frame frequency
this paper puts forward a high speed and parallel image compression system of high integration degree. Firstly
according to the work principle of the area CCD
FPGA is adopted to realize the timing driving and multichannel and parallel analog signal handling to raise the export frame frequency of the area CCD. Secondly
with an image compression scheme based on FPGA embedded processor MicroBlaze and ADV212 compression chip
real time image compression and the high speed area CCD are realized. Finally
by detecting the analog signal of the area CCD output
the real time compression of the big area CCD image is carried out in different compression ratios and the compression performance is analyzed. Experiment result shows that this scheme can realize real time image compression with the biggest data rate of 520Mbps. When compression bit ratio is 0.15
the signal-to-noise ratio of peak value can reach 36 dB. Image collection and image compression are integrated
which reduces the data transmission between them and improves systematic integration degree.

Extreme Ultraviolet Telescope (EUT) will image solar corona in four EUV narrow bandpasses defined by multilayered coatings deposited on normal incidence optics. In order to make sure it will get sub-arcsecond angular resolution in the mission we have to test its resolution performance on ground. The EUT is aligned by Zygo interferometer first and a global wavefront error of 0.152 peak to valley is obtained ( = 632.8nm ). Because of the difficulty of angular resolution test for EUT at its operating wavelengths
we test its optical performance at visible and UV band. The method is to place the resolution test-target on the focal plane of collimator and illuminate the target by visible and UV light espectively
then the collimated light will go through EUT and image at focal plane on CCD. By analysis of the images obtained in experiments we conclude that the angular resolution of EUT is 1.22 at visible light ( = 570nm ) which is very close to diffraction limit (1.20) and according to these results we estimate that the operational wavelength resolution is better than 0.32
meets design requirements. While for UV light
the angular resolution is 1.53 that is different from diffraction limit (0.53)
the error comes mainly from large pixel of EUV camera. 2009 SPIE.
