12035079 · 2024-07-09 · ·

A projection system arranged to receive an image for projection. The image is a colour image comprising a first colour component and a second colour component. The system is arranged to calculate a first hologram of the first colour component and a second hologram of the second colour component. The system is further arranged to add content of the second colour component to the first colour component before calculating the first hologram. The first hologram contains information of the first colour component and information of at least a portion of the second colour component. The system is further arranged to form a first holographic reconstruction by illuminating the first hologram with first colour light and to form a second holographic reconstruction by illuminating the second hologram with second colour light. The first holographic reconstruction changes the chromaticity of the at least a portion of the second colour component.

Holographic image projection with holographic correction

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).

Lighting device for headlights with a phase modulator

There is provided a lighting device arranged to produce a controllable light beam for illuminating a scene. The device comprises an addressable spatial light modulator arranged to provide a selectable phase delay distribution to a beam of incident light. The device further comprises Fourier optics arranged to receive phase-modulated light from the spatial light modulator and form a light distribution. The device further comprises projection optics arranged to project the light distribution to form a pattern of illumination as said controllable light beam.

20190073831 · 2019-03-07 · ·

A novel 3D mixed-reality space and experience construction sharing system is configured to provide a novel part-holographic and part-physical object-based immersive user experience environment that enables an intermixture of computer-generated lifelike holographic objects and real objects to be synchronized and correlated to a particular physical space (i.e. as a mixed-reality (MR) environment) for vividly-interactive user experiences during a user's visit to the particular physical space. Moreover, the novel 3D mixed-reality space and experience construction sharing system accommodates a user interaction designer to construct and configure a mixed-reality (MR) environment and various potential user interactivities for a geographic landmark, a museum, or another tourist destination, and subsequently share the MR environment with other user interaction designers and users (e.g. tourists) who visit that tourist destination. Typically, the MR environment is visualized through a head-up display device or another portable electronic device executing an MR environment-visualization mobile application.

Holographic keyboard display

Embodiments that relate to displaying holographic keyboard and hand images in a holographic environment are provided. In one embodiment depth information of an actual position of a user's hand is received from a capture device. The user's hand is spaced by an initial actual distance from the capture device, and a holographic keyboard image is displayed spatially separated by a virtual distance from a holographic hand image. The user's hand is determined to move to an updated actual distance from the capture device. In response, the holographic keyboard image is maintained spatially separated by substantially the virtual distance from the holographic hand image.
