Perceived Image Depth for Autostereoscopic Displays
InactiveUS20150015946A1Reduce optical aberrationMore field of viewOptical elementsDisplay designDisplay device
An autostereoscopic display provides an extremely deep projection area by observing a relationship between a desired depth of projection and an autostereoscopic display design that includes a focal length of lenticles of a lenticular array and a number of views. The relationship specifies a projected depth at which lenticular crossover can occur for a given autostereoscopic with the specific lenticular focal length and number of views. Approximations can be used to simplify the relationship such that the projected depth is directly related to a product of the focal length and the number of views. To reduce optical aberrations, lenticles of the lenticular array include meniscus-cylinder lenses.

Fiber coupled artificial compound eye
InactiveUS7376314B2Sharpen imageReduce optical aberrationAdditive manufacturing apparatusCoupling light guidesDistortion freeDetector array
A multiple aperture array, wide angle imaging system incorporates compound refractive optics modeled after the eyes of insects. The system channels light through the apertures of a convex spatial filter and a pair of lenslet arrays hot press molded on a positive meniscus form. The lenslets act as afocal Keplerian telescopes to superpose light from hundreds of adjacent channels to a common point on the convex surface of a fiber optic imaging taper. The superposed light from all the channels form a curved, high intensity image that is transformed by the taper into a flat format for readout by a mosaic detector array. The image is upright and distortion free with an infinite depth of field. Ghost images are blocked by a honeycomb louver baffle positioned between the lenslets and the imaging taper. The system is conformable to the geometry of any convex mounting surface, whether spherical, aspherical, or cylindrical.

Adaptive optical devices with controllable focal power and aspheric shape
A fluidic lens may include an optical surface configured for deflection dominated by bending stress. An adjustable concentric load may be applied to the optical surface to cause a clear aperture region of the optical surface to deflect with generally spherical curvature. Adjusting the concentric load controls the radius of curvature. An adjustable uniformly-distributed load may be applied to the optical surface by fluid pressure that causes the clear aperture region to deflect with an aspheric shape. Adjusting the pressure controls the asphericity of curvature. First and second fluids having similar densities and different refractive indexes may be disposed on either side of a deflectable optical surface to help balance gravitational loading on either side of the optical surface, thereby reducing gravity-associated aberrations.
