| 摘 要： | 在介绍一种利用InGaAs/I半导体激光器并采用钽酸锂热释电探测器实时测量比辐射率及温度的系统的基础上，着重讨论了从光、电干扰及其抑制这两方面所采取的提高其采样精度的措施：一是在抑制光干扰的基础上选择合适的采样时机并优选采样结果；另一是在抑制电干扰的基础上选择合适的采样周期并进行信号平均。给出了系统的采样硫程图，进行了一些必要的分析和讨论。

| Abstract: | After introducing the temperature real-time measurement system using lasers and pyroelectric detector,this paper mainly discusses measures taken on improving sampling accuracy:One is selecting suitable sampling opportunity and optimizing sampling results based on restraining light interference,the other is selecting sampling period and taking average on sampling frequency based on restraining electric disturbance.Sampling schematic diagram of the system,some necessary analyses and discussions are given. |
