The central one of the fiber probe is used for transmitting laser beam, the others having same spaces to the center one are used for receiving scattered signal.
在装置中间，其中一根光纤用于传输入射激光，周围多根光纤与中心光纤等间隔，用于接收血液中的散射光。
However, the scattered light is extremely weak and therefore yields a very low signal.
然而，这种散射光极其微弱，因此只产生一个非常弱的信号。
Going even lower, there is a more subtle, scattered, and more medially distributed region of abnormally high signal.
在向更低的平面，可以看到异常高信号散落分布在一些细小区域。
After a signal is sent off, the ravenous vultures swoop down and peck at the flesh and the bones scattered around.
发出信号后，饥饿的秃鹫俯冲下来啄食尸肉和散落在周围的骨头。
And because the big diameter lens is used to collect scattered light, the Doppler signal of high SNR is obtained.
使用大口径透镜收集散射光得到高信噪比的多普勒信号。
At least one receiving transducer is positioned to receive scattered energy to generate a range gated Doppler signal.
至少一个接收传感器定位成接收所散射的能量从而生成范围选通多普勒信号。
In ideal circumstances, the back scattered echo signal of SAR is chirp signal. With synthetic aperture theory, high azimuth resolution imaging to distant targets can be attained.
理想情况下，SAR回波多普勒信号是线性调频信号，采用合成孔径原理提高方位向成像分辨率。
Pulssar signal will be scattered as it passes through the Interstellar medium, what is called dispersion.
