1. A Michelson type interferometer with the maximum optical path difference of 220 cm in the far infrared region is fabricated. A Fourier transform spectrometer using the interferometer is under construction.2. Properties of coherent synchrotron radiation such as absolute spectral intensity, degree of polarization and temporal coherence have been studied experimentally, using linear accelerators. The radiation is verified to be an excellent optical source with high brightness in the submillimeter and millimeter wavelength region. It is also observed that radiation intensity of coherent transition radiation is the same order of magnitude as that of coherent synchrotron radiation in the far infrared.

1. 制作了远红外区域最大光程差为220 cm的迈克尔逊型干涉仪。采用干涉仪的傅里叶变换光谱仪正在建设中。 2．使用线性加速器对相干同步加速器辐射的特性（例如绝对光谱强度、偏振度和时间相干性）进行了实验研究。该辐射被证实是一种在亚毫米和毫米波长区域具有高亮度的优秀光源。还观察到相干跃迁辐射的辐射强度与远红外相干同步辐射的辐射强度处于同一数量级。
