Figure 1 shows a schematic for an ideal current source driving a resistor load.
图1 显示了一个理想的电流源驱 动的电阻负载的原理图。
In an optical current sensing system, when the fluctuations of the driving current or the ambient temperature of the optical source used happens, the peak wavelength of the source will change.
在光学电流传感器系统中，光源的驱动电流与环境温度改变，都会造成光源峰值波长移动。
Therefore, it is necessary to stabilize the driving current and the ambient temperature of the optical source by some technical means.
因此，光源的恒温控制与光源驱动电流的恒流控制是必要的。
