在操作中，微弱电流通过元件，电压与电阻正比，然后测量并转换为温度校正的组件。
In operation, a small excitation current is passed across the element, and the voltage, which is proportional to resistance, is then measured and converted to units of temperature calibration.
最后设计了红外成像系统与PC机的串口通信，通过串口，PC机可以远距离对红外成像系统进行非均匀性校正、坏点校正、视场切换、调焦等操作。
Through serial communication port, PC machine can make the infrared imaging systems to achieve non-uniformity correction, bad point correction, switching field of view, focusing and other operations.
