本文报道了利用傅里叶变换方法测量红外辐射源分谱能量分布的基本原理和实验方法,着重讨论了测量系统的仪器响应特性对测量结果的影响及改进措施,最后就两个测量实例作了具体讨论。
This paper reports the basic principles and experimental methods of using Fourier transform to measure the energy distribution of the infrared radiation source. The effects of the instrument response characteristics of the measurement system on the measurement results and the improvement measures are discussed. Finally, two measurement examples are made Specific discussion.
