摘要：
In this work an alternative method has been described for refractive index measurement of a blue phase liquid crystal in the Kerr effect. The proposed wedge method uses a simple goniometric setup, allowing for direct index measurements for any wavelengths and index values. This is a significant advantage comparing to other methods, usually having limitations of the measurement range as well as requiring complicated calculation to obtain refractive index values. The results are reliable and agree well with subject literature. © 2017 Photonics Society of Poland.
