摘要： There is provided a method of projection using an optical element (502,602) having spatially variant optical power. The method comprises combining Fourier domain data representative of a 2D image with Fourier domain data having a first lensing effect (604a) to produce first holographic data. Light is spatially modulated (504,603a) with the first holographic data to form a first spatially modulated light beam. The first spatially modulated light beam is redirected using the optical element (502,602) by illuminating a first region (607) of the optical element (602) with the first spatially modulated beam. The first lensing effect (604a) compensates for the optical power of the optical element in the first region (607). Advantageous embodiments relate to a head-up display for a vehicle using the vehicle windscreen (502,602) as an optical element to redirect light to the viewer (505,609).

摘要： A phase-modulated optical component for the visible spectrum is provided and is capable of producing images in three primary colors. The phase-modulated optical component is primarily structured by a plurality of aluminum nanorods that are arranged in several two-dimensional arrays to form a plurality of pixels. The nanorods can yield surface plasmon resonances in red, green and blue light. By tuning the nanorod size in the arrays, the wavelength-dependent reflectance thereof can be varied across the visible spectrum, thereby realizing wavelength division multiplexing operations for the phase-modulated optical component.

摘要： An illumination device has an optical device and an irradiation unit. The irradiation unit has a light source emitting a coherent light beam, and a scanning device capable of adjusting a reflection angle of the coherent light beam emitted from the light source. The light source has light sources emitting a plurality of coherent light beams having an identical wavelength range, the hologram recording medium has a recording area to be scanned with each of a plurality of coherent light beams reflected by the scanning device, and the recording area has an interference fringe that diffracts an incident coherent light beam. The optical device uses the plurality of coherent light beams diffracted by the interference fringe of the recording area so that each of the coherent light beams diffracted by the hologram recording medium is superimposed on at least one portion to reproduce the image of the reference member.

摘要： A method of enlarging an observation window from which the reconstruction from a Computer Generated Hologram (CGH) may be viewed, including reproducing a CGH, and shifting a location of an exit pupil or observation window of an optical system reproducing the CGH. A method of increasing a viewing angle from which the reconstruction from a Computer Generated Hologram (CGH) may be seen, including producing a plurality of instances of a CGH, projecting each one of the instances in a different direction so that a first exit pupil of a first instance is close to a second exit pupil of a second instance. An optical system including a plurality of exit pupils associated with a plurality of optical components, further including a light deflector for jittering a location of a first exit pupil so as to increase an overlap of the first exit pupil with a second exit pupil. Related apparatus and methods are also described.
