Yago Arosa, Carlos Damián Rodríguez-Fernández, Alejandro Doval, Elena López Lago, Raúl de la Fuente

摘要:

对光谱分辨白光干涉法测量色散时折射率和群折射率的不均匀性进行了深入分析。首先,影响两个指数的不同参数的不确定性的贡献被确定。之后,结果为1.5毫米厚的熔融石英样品在一个广泛的光谱范围内,从400至1000纳米,和主要恶化的测量精度的影响建立。最后,不同的贡献二次合并,以确定两个指数的总不确定性。

英文摘要:

Uncertainties of refractive and group index in dispersion measurement by spectrally resolved white light interferometry are deeply analyzed. First, the contribution to uncertainty of the different parameters affecting both indices is identified. Afterwards, results are presented for a 1.5 mm thick fused silica sample over a broad spectral range, from 400 to 1000 nm, and the effects that mostly deteriorate the measurement accuracy are established. Finally, the different contributions are quadratically combined to determine the total uncertainty of the two indices.
