摘　　要：分析了光热辐射测量（ＰＴＲ）系统中温度场的分布特性及系统的传递函数对检测系统空间分辨率的影响．采用微分消卷积方法对实测曲线进行处理，结果表明。The characteristic of the temperature field distribution of the photothermal radiometry (PTR) system and the effect of transfer function of the PTR system on the spatial resolution were analyzed.The derivative deconvolution method was applied to improve the spatial resolution of the real measurement curves.The results show that the derivative deconvolution can enhance the spatial resolution of the PTR system effectively.
