用热图象器测定从人体表面放射出来的红外线,近年来广泛用于临床诊断,作者对面神经麻痹的患者,用此法通过了解面部温度改变,来估计预后和选择适当的治疗方法。热图象利用物体放射出来的红外线,经过扫描集光系统,将光集中起来再转换为电信号,经电系统处理予以增幅并进行温度校正后,在显象管上呈象,然后再用偏光照相机摄影。这种检查 In recent years, it has been widely used in the clinical diagnosis of the patients with facial nerve paralysis. This method is used to understand the prognosis of the facial nerve and estimate the prognosis and select the appropriate treatment method by using this method to measure the infrared radiation emitted from the human body surface. Thermal images using objects emitted from the infrared, after scanning the light collection system, the light together and then converted to electrical signals, the electrical system to be processed to increase and temperature correction, the CRT image, and then use the polarized light Camera photography.
