Wireframe holography as a method for augmented reality projections
Abstract:
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.

Posttensioned Masonry Walls
Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...
