在核探测器和前置放大器获取核信息及波形数字化系统将模拟核信号数字化的过程中，都不可避免地会使核信号发生畸变，影响测量结果的精度。
During the detector and preamplifier acquire nuclear information and WDS convert the analog signals to digit value, the nuclear signals will inevitable be distorted to make the final result worse.
微型光谱仪通常采用光电探测器阵列作为光谱信号获取元件，将光谱信号转化为电信号。
Micro spectrometer generally takes the SSPA (self scanned photodiode array) as sensor to turn the spectrum signal into a form of electrical signal.
视觉信号具有信号探测范围宽、获取信息丰富等优点。
