电源技术 光纤激光器的电流源分析
 
A large group of fiber optic lasers are powered by DCcurrent. Laser drive is supplied by a current source withmodulation added further along the signal path. Thecurrent source, although conceptually simple, constitutesan extraordinarily tricky design problem. There are anumber of practica ...

When trying to extract information from SAR images, we need to distinguish
two types of image property. The more important is where properties of the
scene (e.g., its dielectric constant, its geometry, its motion, etc.) produce effects
in the image measurements or examination of the image then can ...
