ENHANCEMENT OF SPATIAL RESOLUTION OF PTR SYSTEM USING THE DERIVATIVE DECONVOLUTION
微分消卷积法提高PTR检测系统空间分辨率的研究

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.
