  • Publication number: 20250199329
    Abstract: Light-field image projection system having a light source with a single narrow band point light source per color emitting narrow-band light, a splitting device sequentially generating incident light beams and form virtual light sources, a spatial light modulator generating a modulated beam light and a virtual image for each incident light beam; and a combiner projecting the virtual images at virtual viewpoints within an eye box region and transmitting natural light from the real world towards the eye box, each viewpoint containing an image of the virtual scene viewed from that viewpoint. The splitting device directs the incident light beams to the spatial light modulator such that the incident light beams are incident on the surface of the spatial light modulator at different angles of incidence. the ratio of luminous intensity of a single virtual light source over the luminous intensity of the narrow-band light is at least 1%.

  • Publication number: 20250108385
    Abstract: An installation is provided that is intended to separate two families of components of a mixture placed in a receptacle. The installation is provided with a screen and comprises a first electrode, a second electrode, and a generator that generates, between the first and second electrodes, an agitating alternating electrical field. The alternating electrical field is capable of alternately projecting all or some of the components of the mixture that is present in the receptacle towards or against the first electrode and then towards or against the second electrode in order to generate mechanical impacts on the components that contribute to breaking down the mixture within the receptacle and in order to facilitate the passage of components belonging to the second family through the screen. The screen ensures components belonging to the first family are retained in the receptacle.

  • Patent number: 11762262
    Abstract: A cavity-enhanced frequency mixer includes an input optical fiber, a waveguide, and an output optical fiber. The waveguide has an input end and an output end, the input end is connected to the input optical fiber, and a surface of the input end of the waveguide is coated with a highly reflective coating. The output optical fiber is formed with a fiber Bragg grating structure. The highly reflective coating and the fiber Bragg grating structure form a pair of reflective surfaces for resonant optical parametric oscillation under a low threshold situation, so that one of the beams generated by the input beam is reflected inside the partially reflective surfaces. Operated above a pump power threshold, the cavity-enhanced frequency mixer is tantamount to a compact, low-power budget optical parametric oscillator, while below the pump power threshold, it is a bright, compact, single-mode and narrow linewidth single-photon source.
