Lithium fluoride (LiF) crystal is a very promising candidate as nanometer resolution EUV and soft X-ray detector. Compared with other EUV and soft X-ray detectors
charge coupled device and photographic films
LiF crystal has high resolution
large field of view and wide dynamic range. In this paper
using LiF crystal as EUV detector and a Schwarzschild objective (SO) working at 13.5nm as projection optics
mesh images with 4.2 m
1.2 m and 800 nm line width and pinhole patterns with 1.5m diameter are acquired in projection imaging mode and direct writing mode
respectively. Fluorescence intensity profiles of images show that the resolution of mesh image is 900 nm
and the one of pinhole image is 800 nm. In the experiments
a spherical condense mirror based on normal incidence type is used to eliminate the damage and contamination on the masks (mesh and pinhole) caused by the laser plasma
and the energy density is not decreased compared with that the masks are close to the plasma. The development of the SO
the alignment of the objective and the imaging experiments are also reported. 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

A set special detecting system is proposed based on TDICCD push-broom technology applying in dynamic imaging detecting experiment of space optics remote sensor. In the system
In the course of detecting
push-broom movement of the satellite is simulated through using double supporting U structure precision rotary platform with remote sensor by angular speed 0.555/s
regard Nyquist frequency target as detecting aim
within the range of 5 and control precision on steady speed achieves 0.3%
in order to solve matching uncertainty between the CCD pixel and the vertical target strip image when the remote sensor does push-broom
make matching simplify
enhance the measurement result the accuracy. So the tolerance a/n arithmetic progression gap target strip is joined in each group of rectangular vertical group target strip. The remote sensor obtains in vertical
the level and 45 the direction 0 fields of view
0.86 the field of view Nyquist frequency target strip image after detected
a group target strip which can precision matching to TDICCD pixel at least can be obtained through analysis and dealing with 0.86 field of view's target strip image. The experiment not only verifies the detecting system's feasibility but simultaneously verifies whether to have the high quality dynamic imaging quality when TDICCD push-broom technology is adopted on the remote sensor developed. 2010 Copyright SPIE - The International Society for Optical Engineering.

An imaging system with three-waveband sharing one lens and an area CCD was developed. By rotating different filters into the beam path
the required waveband was selected. The optical system which can image in ultraviolet
visible and near infrared region was designed and the signal collecting system was integrated. The optical design and system integration have some advantages such as low cost
small size and light in weight. To obtain a high imaging quality
the radiation calibration is carried out in order to establish the relation between the average grey level of output image and the input radiance from the integrating sphere. According to the calibration data in experiments
the radiation dynamic range and the best working point of the system are determined. The experiment result shows that the dynamic range of the image system is maximal when the exposure time is 8ms in ultraviolet
0.5ms in visible and 0.125ms in near infrared region. 2010 IEEE.
