摘要
Abstract
The compensation effect for refractive index of air is the "bottle neck" factor in improving the accuracy of interferometric measurement. The theory of compensation for refractive index of air is analyzed. Several methods for measuring refractive index of air are analyzed and effectiveness of compensation is compared. Based on these results, an interferometric device to measure the refractiv e index of air without air evacuation in the measuring process is studied. A pre-evacuated airtight sealed chamber with 45° slope is employed. It is testified that the method is effective and the measuring accuracy is improved by the experi ments of measuring and compensating for refractive index of air.关键词
