摘要:
A holographic display includes a pixel array including one or more pixels, a holographic data source, a drive array, and a light source. Each pixel includes a phase-modulating structure and an amplitude-modulating structure. The holographic data source is configured to supply a holographic drive signal. The holographic drive signal includes, for each pixel in each of a plurality of time-varying holographic image frames, a phase component defining phase modulation for the pixel and an amplitude component defining amplitude modulation for the pixel. The drive array is configured to, for each pixel in each holographic image frame, modulate the phase-modulating structure according to the phase component and modulate the amplitude-modulating structure according to the amplitude component. The light source is configured to output coherent light to illuminate the one or more pixels of the pixel array.

A solar powered variable light attenuating device includes a liquid crystal cell, a photovoltaic cell in electrical communication with the liquid crystal cell, and a light concentrator having a light absorbing surface and a light emitting surface optically coupled to the photovoltaic cell. At least a portion of light impinging on the light absorbing surface of the light concentrator is concentrated and directed through the light emitting surface to a photon- absorbing portion of the photovoltaic cell to generate a voltage. The generated voltage is used to change the liquid crystal cell from a de-energized state to an energized state in response to sunlight directed toward the photovoltaic cell.
