Wireframe holography as a method for augmented reality projections

Computer-generated holography (CGH) faces challenges related to high computational demands and speckle noise that degrade image quality. This paper presents "wireframe holography", a method that builds upon point-cloud techniques by using linear segments as building blocks, which are formed by introducing controlled astigmatism in phase profiles. This approach reduces both computational costs and speckle noise, enabling the creation of more complex 3D objects with comparable performance to traditional methods. Compatible with existing superposition algorithms, such as Random Superposition and Gerchberg-Saxton-based techniques, this method offers improvements for applications in augmented reality and any field requiring efficient, high-quality holographic imaging.
