Claim Text:
1. A spatial stereoscopic display device, comprising: a laser source, connected with a 3D modulator and emitting laser light; a two-dimensional scanning unit, connected with the 3D modulator and receiving the laser light emitted by the laser source and projecting the laser light onto a variable isoclinic transflective unit according to specific addressing information under the control of the 3D modulator; the variable isoclinic transflective unit, receiving the laser light projected thereon by the two-dimensional scanning unit and dividing the laser light into a first splitting light and a second splitting light intersecting in an imaging space, by transmission and reflection; a power source and position sensor unit, connected with the variable isoclinic transflective unit to control an intersection of the first splitting light and the second splitting light in the imaging space; the imaging space, provided with an up-conversion material inside, and the up-conversion material at the intersection of the first splitting light and the second splitting light is excited to form a light-emitting point; and the 3D modulator, connected with the laser source, the two-dimensional scanning unit, the power source and position sensor unit to respectively control the laser source, the two-dimensional scanning unit, the power source and position sensor unit, wherein the variable isoclinic transflective unit includes a transflective film and a reflector arranged under the transflective film; the laser light from the two-dimensional scanning unit is directly projected onto the transflective film; and the reflector is obliquely arranged at an initial inclination angle relative to a plane where the transflective film is positioned, the reflector is movable, and there are a plurality of light-emitting points in the imaging space to provide a volumetric three dimensional image being consistent with a motion trajectory of the intersection of the first splitting light and the second splitting light.
