Abstract
A collapsible pyramid holographic projection imager includes a pyramid imaging member and a bottom fixing member, where the pyramid imaging member includes two support plates and a holographic projection film; a middle of the support plate is shaped as a crisscross framework; the holographic projection film is fixed between the two support plates; four pre-cuts are formed in the bottom fixing member; in response to a collapsed state of the collapsible pyramid holographic projection imager, the pyramid imaging member and the bottom fixing member are placed independently in a sheet manner; and in response to an expanded state of the collapsible pyramid holographic projection imager, the collapsible pyramid holographic projection imager assists an image generation device, and a video or an image played by the image generation device is projected to the collapsible pyramid holographic projection imager to form a three-dimensional (3D) image.
