Abstract

We proposed a DHM system with improved spatial resolution compared with that of the polarized camera-based DHM system by employing a liquid crystal phase modulator (LCPM). The LCPM-based holographic interferometry optical system can reliably construct a four-step phase shifting scheme by changing the applied voltage, thus eliminating the need for mechanical moving parts. The spatial resolution characteristics of the proposed DHM system were analyzed using the 1951 USAF resolution target. These characteristics showed a fourfold improvement over the polarized camera-based DHM system. Additionally, the 3D information capturing capability of the proposed DHM system was experimentally confirmed using a via-hole array sample produced through the semiconductor fabrication process.

利用液晶相位调制器开发空间分辨率增强型数字全息显微镜

通过采用液晶相位调制器（LCPM），我们提出了一种与基于偏振相机的 DHM 系统相比空间分辨率更高的 DHM 系统。基于液晶相位调制器的全息干涉光学系统可通过改变外加电压可靠地构建四步移相方案，从而无需机械运动部件。利用 1951 年美国空军分辨率目标分析了拟议 DHM 系统的空间分辨率特性。与基于偏振相机的 DHM 系统相比，这些特性提高了四倍。此外，通过使用半导体制造工艺生产的通孔阵列样品，实验证实了拟议的 DHM 系统的三维信息捕获能力。
