### **1. Introduction**

Modern holographic techniques have been successfully applied in many important areas, such as 3D inspection, 3D microscopy, metrology and profilometry, augmented reality, and industrial informatics. This Special Issue covers selected pieces of cutting-edge research works, ranging from low-level acquisition, to the high-level analysis, processing, and manipulation of holographic information. The Special Issue also serves as a comprehensive review on the existing state-of-the-art techniques in 3D imaging and 3D display, as well as a broad insight into the future development of these disciplines. The Special Issue contains 25 papers in the field of holography, 3-D imaging and 3-D display. All the papers underwent substantial peer review under the guidelines of *Applied Sciences*. The twenty-five papers are divided into three groups: holography, 3-D imaging, and 3-D display.
