For the non-function intensity type fiber optic sensors, the main intensity errors are caused by the variation of (1)source device output optical power;
在非功能式强度型光纤传感器中，造成光强变化而导致较大信号误差的主要原因有如下几个方面：（1）光源输出光功率的变化；
Such a theoretical device would have a zero ohm output impedance in series with the source.
这种理论的设备将有一个与源系列零欧姆的输出阻抗。
The device has the advantages of long service life, high light emission efficiency and stable light output, and can meet the illumination requirement for backlight source of LCD device, etc.
且该装置使用寿命长、发光效率高、输出光稳定，适合作为LCD显示器件的背光源等照明要求。
