摘要:
The invention relates to a holographic information display for a motor vehicle for projecting a virtual display element. A data processing device provides a hologram for the virtual display element to be projected. A control device in each case emits an individual control signal for a plurality of segments of the hologram. A plurality of optical phase delay cells which can be individually adjusted by the control device and are arranged on a face illuminated by the light beam, delay the fraction of the light beam incident thereon in each case in the phase in response to the respective individual control signal.
