The present disclosure provides a mobile terminal comprising: a main body of the terminal; a holography module attached to the main body of the terminal and positioned so as to output a holographic image into a preset space; and a first camera module arranged in the direction of the preset space so as to film the holographic image. Also, the present invention provides a system for controlling holography comprising the mobile terminal and a target apparatus. The target apparatus is configured so as to film the holographic image by communicating with the mobile terminal or to analyze the holographic image and generate an operational command corresponding thereto.

A holographic image recording method is disclosed, that is realized through utilizing a holographic image fetching and recording device, including the following steps: using an image fetching device to fetch an image of a target object placed on a rotation table rotating at a fixed speed, the image thus obtained is transmitted to a display panel through a connection line; using a light emitting unit to emit coherent light to a first reflector; that reflects the coherent light to light splitter; and the light splitter splits the coherent light along a first light path and a second light path into an object light and a reference light, and transmits them onto a holographic film to interfere with each other, to form a holographic image. A holographic image reconstructing method is also disclosed, to reconstruct and form a 3D holographic image floating above the holographic film.

A system and method of providing internet-based teaching utilizing a holographic projection is disclosed. The system receives a query from a user via a user device. The system parses the query and generates a response to the query. The system generates a holographic image emulating a real-life educator. Further, the system generates a voice response corresponding to the response. The system integrates the holographic image and the voice response and presents it at the user device in order to create an impression that a real-life professor responded to the query. The system captures the essence of in-person instruction, offering students a uniquely engaging and adaptive educational journey in the digital realm.
