  • Patent number: 12372348
    Abstract: A system for dynamic profilometric imaging using multiscale pattern(s) is described. The system may include a projector that projects a multiscale pattern on an environment including a target of interest. The system may also include an imaging sensor that receives reflections of the projected multiscale pattern from the target of interest. The system may further include a controller of the camera and the projector which performs profilometric imaging of the target of interest by dynamically adjusting an operational parameter of the camera, the projector, and/or the controller. The multiscale pattern(s) may contain useful features at multiple scales and/or may be optimal at predetermined depths and/or resolutions. By dynamically adjusting the operational parameter, such a profilometric imaging system may perform there-dimensional (3D) scene reconstruction while maintaining optimal performance, power efficiency and profilometric resolution.

  • Patent number: 12360368
    Abstract: A varifocal liquid lens includes a body filled with two different fluids separated by an interface of a variable curvature across a clear aperture of the varifocal liquid lens. At least one of the first or second fluids is birefringent, such that a refractive index difference between the first and second fluids and resulting optical power of the varifocal liquid lens is dependent on polarization of impinging light. At a first light polarization, the first and second fluids may be matched in refractive index, while at a second, orthogonal light polarization, the first and second fluids may be mismatched in refractive index, whereby the first interface between the first and second fluids may have a variable, non-zero optical power for the second polarization while having a substantially non-variable, zero optical power for the first polarization of light.
