Apparatus for reading a hologram
摘要:
An apparatus for reading a hologram, in particular a computer-generated hologram, that includes a radiation source for irradiation of the hologram with a read beam composed of electromagnetic radiation, and an outlet opening for receiving an image that is produced from the hologram. The apparatus may allow both greater variability and greater convenience in use with a simple design. The apparatus further includes optics having at least two lenses in which a focal point of the first lens and a focal point of the second lens are each arranged essentially on one plane, and in which the hologram is arranged in front of the second lens as viewed along the beam direction.
