Digital Holography and its Applications in Industrial Inspection

Digital holography (DH) acquires and processes holograms with digital cameras and computers, providing the full information, including amplitude and phase, of an optical wave. Notably, the reconstructed phase image allows quantification of the three-dimensional surface or thickness distribution of an object, as well as refractive index distributions. Many efforts have been made to enhance the spatial resolution, imaging speed, phase accuracy, and measurement range of DH in general. The concept of DH has been enriched with many revolutions, such as incoherent DH, compressive DH, DH imaging through scattering medium, entanglement-enabled quantum holography. Meanwhile, dozens of image processing algorithms, including machine learning, deep learning technologies, bring as well new breakthroughs to DH. To date, DH has been considered an important measurement tool for 3D surfaces, thickness, vibration, strain/stress, and refractive index distributions at various industrial sites, as well as for in situ and real-time monitoring of the processes involved in the fabrication cycle.

The core of this session relates to the latest development of DH and its application in industrial inspection. Submissions are solicited on, but not limited to, the following topics:
