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... Two Trees Photonics Limited

2d/3d holographic display system

A display system (300) comprising an optical system and a processing system. The optical system comprising a spatial light modulator (380), a light source, a Fourier transform lens, a viewing system (320, 330) and a processing system. The spatial light modulator is arranged to display holographic data in the Fourier... Two Trees Photonics Limited

Head-up display with diffuser

There is provided a head-up display for a windscreen having spatially variant optical power. The head-up display comprises a diffuser arranged to display an image. The diffuser is shaped to compensate for the spatially variant optical power of the windscreen. A holographic projector may be provided, which is arranged to... Two Trees Photonics Limited

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... Two Trees Photonics Limited

Imaging device for moving a virtual image

There is provided an imaging device. The imaging device comprises a projection optic arranged to form a virtual image of an object. The imaging device further comprises a first diffuser positioned a first distance from the virtual projection optic and a second diffuser positioned a second distance from the virtual...

Image phase retrieval

A method of processing a pixellated image to retrieve a phase distribution representative of the image. The phase distribution representative of the image is in the Fourier domain. The method includes padding the image pixels with padding, or non-image, pixels to increase the total number of pixels in the pixellated... Two Trees Photonics Limited
