AUTOMATIC REGISTRATION OF GF4 PMS: A HIGH RESOLUTION MULTI-SPECTRAL SENSOR ON BOARD A SATELLITE ON GEOSTATIONARY ORBIT
GF4 PMS Automatic Image Registration Optimal Base Band RPC Correction Spatial Resolution
2018/5/14
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 ...
We have developed compact 12-channel, on-board optical transmitters and receivers.The assembly size was 9 mm x 14 mm. Error-free transmission up to 20 Gb/s/ch was achieved,which will enable us to cons...
Characterization of a MEMS Based Optical System for Free-Space Board-to-Board Optical Interconnects
Free-space optical communication Alignment
2015/6/9
We demonstrate alignment of an array of VCSELs to detectors, using a MEMS-based lens system for free-space board-to-board optical interconnects. Our optical system is capable of aligning up to 5 degre...
