SKEWED SECTIONAL MEASUREMENT OF STRIATED GLASS |
摘要 |
Thickness and group index variations in test strip samples of ultra-low expansion glass are made by extracting the strip samples with front and back faces oriented at an acute skew angle to the axis of the boule. The strip samples are positioned the within an interferometric measurement cavity so that a set of subcavities formed by pairings of each of two reference surfaces together with each of the front and back faces of the strip sample which each subcavity having a different optical path length spacing. The skew angle is sized to avoid diffusion effects of striae present in the boule. |
