Combining the ideas behind linear frequency modulated continuous wave radars and frequency domain photothermal radiometry (PTR), a novel PTR method is introduced. Analytical solutions to the heat diffusion problem for both opaque and transparent solids are provided. Simulations and experimental results suggest a significant improvement in the dynamic range when using the thermal-wave radar (TWR) instead of conventional PTR. A practical TWR image resolution augmentation method is proposed.
结合线性调频连续波雷达和频域光热辐射测量法（PTR）背后的理念，引入了一种新颖的PTR方法。给出了不透明和透明固体热扩散问题的解析解。模拟和实验结果表明，使用热波雷达（TWR）代替传统PTR时，动态范围有显著提高。提出了一种实用的TWR图像分辨率增强方法。
