摘要： This invention relates to holographic image display systems. We describe an optical module for a holographic image projection system which displays a hologram (204) of a low spatial frequency portion of input image data on an SLM (SLM1) to form a holographically-generated intermediate real image which is in turn modulated (SLM2) by a higher spatial frequency portion of the image data (206), to display the image. The optical module comprises: at least one laser light source; a first spatial light modulator (SLM1) to modulate light from said at least one laser light source; intermediate optics (L4) to provide an intermediate real image plane at which a real image produced by a hologram on said first SLM is formed; a second SLM (SLM2) located at said intermediate real image plane to intensity modulate said real image; and output optics (L5,L6) to project an image of said intensity modulated real image; and wherein a resolution of said second SLM is greater than a resolution of said first SLM.

摘要： The invention relates to a device for reading out a hologram (9), in particular a computer-generated hologram (9), comprising a radiation source for irradiating the hologram (9) with a readout beam (10) of electromagnetic radiation and an exit opening (2) for receiving an image that is generated by the hologram (9). The invention aims to solve the technical problem of providing a device of this type for reading out a hologram, which allows more flexibility and provides greater convenience during use and which has at the same time a simple construction. To achieve this, the device is provided with an optical system that comprises at least two lenses (12, 16), a respective focal point of the first lens (12) and second lens (16) being located essentially on one plane (13). The hologram (9) is positioned in front of at least the second lens (16), when viewed from the direction of the beam.
