摘要

在空间光调制器（slm）中使用蓝相液晶（bplc）由于其与偏振无关的特性，比传统的向列相液晶具有优势。我们演示了一种简化的反射模式设置，类似于硅基液晶（LCoS）技术来评估BPLC的性能。使用纯BPLC的垂直场开关（VFS）反射电池，我们实现了相位调制，而无需在VFS配置中使用BPLC通常需要的复杂电池制造方法。我们的测量验证了该装置在表征BPLC电光响应方面的有效性。测量的Kerr常数K≈4.4 nm V-2证明了该方法用于开发基于bplc的SLMs的可行性。

Experimental Kerr constant determination for pure blue phase liquid crystal: oblique incidence in a reflective vertical field switching cell.

The use of blue phase liquid crystals (BPLCs) in spatial light modulators (SLMs) offer advantages over traditional nematic LCs due to their polarization-independent behavior. We demonstrate a simplified reflection-mode setup similar to liquid crystal on silicon (LCoS) technology to evaluate BPLC performance. Using a vertical field switching (VFS) reflective cell with pure BPLC, we achieve phase modulation without complex cell fabrication methods typically needed for BPLCs in VFS configurations. Our measurements validate the setup's effectiveness in characterizing BPLC electro-optic response. The measured Kerr constant of K ≈ 4.4 nm V^-2 demonstrates this approach's viability for developing BPLC-based SLMs.
