Latest Patents

Pégard holds a patent for "High-speed computer generated holography using convolutional neural networks." The goal of this technology is to synthesize custom illumination patterns by shaping the wavefront of a coherent light beam. Traditional algorithms for computer-generated holography (CGH) often rely on iterative optimization, which presents a trade-off between hologram fidelity and computation speed. This limitation makes them less suitable for high-speed applications such as optogenetic photostimulation, optical trapping, or virtual reality displays. Pégard's proposed algorithm, DeepCGH, eliminates the need for iterative exploration, allowing for the rapid synthesis of high-resolution holograms with fixed computational complexity. This unsupervised model can be tailored for specific tasks using customizable training data sets and an explicit cost function. Results indicate that DeepCGH computes 3D holograms at record speeds and with improved accuracy compared to existing techniques.
