Latest Patents

One of Caulfield's latest patents involves waveguide hologram illuminators. This innovative system utilizes thin substrate waveguides that bear a hologram on their surface, allowing light to be diffracted out. A light source is optically coupled to the waveguide, enabling the emitted light to propagate along the waveguide and be diffracted at intersections with the hologram surface. This selective emission can effectively illuminate display holograms or spatial light modulators. Additionally, provisions are made to ensure that the light emitted through the hologram is uniform along its length.
