What are smart glasses? You might think you already know the answer, but today, it's actually much more complex than it seems. Some people define smart glasses as any pair of "glasses" that have built-in technology, such as digital displays, computer chips, cameras, and microphones. Others, like Met

Earlier, we published an article titled "Comparison of Performance Characteristics of Resin, Glass, and Silicon Carbide Waveguides". Today, we will introduce the three materials in more detail.

In our previous article, "What is AR Diffractive Waveguide?", we explained the fundamental principles of diffractive waveguides and highlighted the differences between surface relief grating waveguides and volume holographic grating waveguides. Today, we will delve deeper into the core functions and

Diffractive waveguide is a mainstream optical display solution for AR glasses. Many AR devices adopt this technology. Why are major AR hardware manufacturers so fond of diffractive waveguides? What exactly is a diffractive waveguide?

AR glasses are set to usher in the next revolution in information technology. Information serves as the foundation for humanity's understanding of the objective world and its developmental patterns, while information technology acts as the primary driving force behind the advancement of human civili
