Abstract

A point-diffraction interferometer is established,which is based on a polarizing mask and the circular common-path setup.The fringe visibility can be adjusted by rotating the polarizer to change the relative intensities between the test and the reference beams.The fringe pattern with the highest visibility is acquired,and the fringe visibility is also analyzed theoretically in detail.The linear carrier frequency may be easily adjusted in the optical system,so the extraction accuracy of the Fourier-transform method is effectively improved.A validated experiment is accomplished.

圆形共程点衍射干涉仪

建立了一种基于偏振掩模和圆形共程设置的点衍射干涉仪。条纹可见性可以通过旋转偏振片来改变测试光束和参考光束之间的相对强度来调节。获得了能见度最高的条纹图，并对条纹的能见度进行了详细的理论分析。线性载波频率在光学系统中易于调整，从而有效地提高了傅里叶变换方法的提取精度。并进行了验证实验。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
