Abstract:
The present disclosure discloses a hologram recording device and a hologram recording method. The hologram recording device comprises an object imaging unit comprising a cavity for accommodating an object whose interior wall is a reflective surface, and a light modulating unit configured to produce incident light and reference light interfering with the incident light and to direct the incident light to the object imaging unit. The cavity is provided with an imaging aperture for imaging of the object and at least one light incidence aperture for allowing the incident light to enter the cavity and irradiate on the object, such that an image of the object is formed at a location corresponding to the imaging aperture outside the cavity, and image light produced upon the imaging of the object interferes with the reference light at the location for recording of an image surface hologram.
Abstract:
The embodiments of the present invention disclose a remote conference system and a method of performing the remote conference. The remote conference system includes a first image-displaying system, at a first conference location, configured to display images of a plurality of audiences; a detection system configured to detect motions or poses of at least part of heads of persons in the first conference location; a judgment system configured to judge whether a person who is talking is talking to a certain audience or some certain audiences of the plurality of audiences or is talking to all the audiences based on the motions or poses detected by the detection system; a second image-displaying system, at a second conference location, configured to display special images to the certain audience or some the audiences of the plurality of audiences when the judgment system has judged that the person who is talking is talking to the certain audience or some certain audiences of the plurality of audiences, such that the certain audience or some of the plurality of audiences is/are aware that the person who is talking is talking to him or them. Whereby, target audience(s) in the remote conference may know the person who is talking is talking to him or them.
