DEVICE, METHOD AND APPARATUS FOR GENERATING HOLOGRAPHIC STEREOSCOPIC IMAGES, AND MEDIUM

The present application relates to the field of holographic projections, and discloses a device, method, and apparatus for generating holographic stereoscopic images, and a medium. The device comprises: a machine body, a three-dimensional display screen, and a negative refractive index plate. The interior of the machine body comprises a first cavity and a second cavity the central axes of which have folded angles, wherein a second end of the first cavity is connected to a first end of the second cavity, and a second end of the second cavity is formed with an opening on a side wall of the machine body. The three-dimensional display screen is arranged at the first end of the first cavity, and the negative refractive index plate is arranged between the second end of the first cavity and the first end of the second cavity. The display direction of the three-dimensional display screen faces the negative refractive index plate, and the refraction direction of the negative refractive index plate faces the opening. In the present application, a three-dimensional display screen is combined with a negative refractive index plate, so that a stereoscopic image that has a three-dimensional visual effect may still be obtained from a side view of a displayed holographic stereoscopic image.
