Geometric correction is an important preprocessing process in the application of GF4 PMS image. The method of geometric correction that is based on the manual selection of geometric control points is ...
Automatic Optical PMD Compensator for 40-Gb/s DBPSK and DQPSK with Fast Changing SOP and PSP
Automatic Optical PMD Compensator DBPSK DQPSK Changing SOP and PSP
2008/8/3
We demonstrate a fast-speed PMDC for 40Gb/s DBPSK and DQPSK. The PMDC increases tolerable average PMD of the DBPSK and DQPSK system to 9 ps and 18 ps,respectively.
