	Nanoscale patterns made by using a 13.5-nm Schwarzschild objective and a laser produced plasma source (EI CONFERENCE) 会议论文 OAI收割 Optical Micro- and Nanometrology IV, April 16, 2012 - April 18, 2012, Brussels, Belgium 作者: Wang X.; Wang X.; Wang X.; Wang Z.; Wang Z. 收藏 \| 浏览/下载：41/0 \| 提交时间：2013/03/25 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).
	High precision test method for dynamic imaging of space camera (EI CONFERENCE) 会议论文 OAI收割 2010 IEEE International Conference on Advanced Computer Control, ICACC 2010, March 27, 2010 - March 29, 2010, 445 Hoes Lane - P.O.Box 1331, Piscataway, NJ 08855-1331, United States 作者: Jin L.-X.; Zhang K.; Zhang K.; Zhang K.; Zhang K. 收藏 \| 浏览/下载：33/0 \| 提交时间：2013/03/25 A test method for dynamic imaging of space TDICCD (Time Delay and Integration Charge Coupled Devices) camera was presented in this paper. The test method adopted the PLL (Phase Locked Loop) technology and CMAC (Cerebella Model Articulation Controller) friction compensation as control strategy. Furthermore According to this method a test system for dynamic imaging of space TDICCD camera was designed and implemented. The system simulated the movement of the ground objects relative to the space aerocraft to validate the capability of image speed match and the dynamic imaging quality of TDICCD camera. The design adopted a precision turntable and a drift turntable to simulate the movement around the earth and the drift motion in different latitude due to the rotation of earth of the aerocraft. The turntables were drived by permanent magnet torque motor which was powered by PWM (Pulse Width Modulation). The system adopted DSP (Digital Signal Processor) as the control core and reached a very high performance. The experimental results showed that the steady speed error was better than 0.01 % and the instantaneous speed error reached 0.0267%. The precision of the test system designed met the requirement for dynamic imaging of TDICCD camera. 2010 IEEE.
