	Multi-channel high-speed TDICCD image data acquisition and storage system (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on E-Product E-Service and E-Entertainment, ICEEE2010, November 7, 2010 - November 9, 2010, Henan, China 作者: Li Y.; Li Y.; Li Y.; Li Y. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 For multi-channel high-speed image data of certain space remote sensing camera this paper proposed a new image data acquisition and storage system. First of all the system uses Field-Programmable Gate Array(FPGA) controlling synchronous dynamic random access memory(SDRAM) array to realize the cache of image data then according to the received commands sends certain channel's image data to the acquisition card to write the image data into SCSI hard disk and implements the final storage. A Time Delay Integral Charge Couple Device(TDICCD) image data acquisition and storage system with five channels is developed pixel clock rate is up to 96MHz total effective data rate is up to 2.88Gb/s single channel storage depth is up to 7810 lines. The experimental results indicate that this system work stably high effectively which can meet the requirement of acquisition and storage of multi-channel high-speed TDICCD image data. 2010 IEEE.

	Driving techniques for high frame rate CCD camera (EI CONFERENCE) 会议论文 OAI收割 Electronic Imaging and Multimedia Technology V, November 12, 2007 - November 15, 2007, Beijing, China Guo W.; Jin L.; Xiong J. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 This paper describes a high-frame rate CCD camera capable of operating at 100 frames/s. This camera utilizes Kodak KAI-0340 an interline transfer CCD with 640(vertical)480(horizontal) pixels. Two output ports are used to read out CCD data and pixel rates approaching 30 MHz. Because of its reduced effective opacity of vertical charge transfer registers interline transfer CCD can cause undesired image artifacts such as random white spots and smear generated in the registers. To increase frame rate a kind of speed-up structure has been incorporated inside KAI-0340 then it is vulnerable to a vertical stripe effect. The phenomena which mentioned above may severely impair the image quality. To solve these problems some electronic methods of eliminating these artifacts are adopted. Special clocking mode can dump the unwanted charge quickly then the fast readout of the images cleared of smear follows immediately. Amplifier is used to sense and correct delay mismatch between the dual phase vertical clock pulses the transition edges become close to coincident so vertical stripes disappear. Results obtained with the CCD camera are shown.
