<p>Embodiments of the invention relate to a spatial stereoscopic display device and an operating method thereof. The spatial stereoscopic display device comprises a laser source, a two-dimensional scanning unit, a variable isoclinic transflective unit, a power source and position sensor unit, an imaging space and a 3D modulator, wherein the two-dimensional scanning unit receives laser light emitted by the laser source and projects the laser light onto the variable isoclinic transflective unit according to specific addressing information under the control of the 3D modulator; the variable isoclinic transflective unit divides the laser light projected thereon into a first splitting light and a second splitting light intersecting in the imaging space, by transmission and reflection; the power source and position sensor unit is connected with the variable isoclinic transflective unit to control an intersection of the first splitting light and the second splitting light; the imaging space is provided with an up-conversion material, 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 is connected with the laser source, the two-dimensional scanning unit and the power source and position sensor unit.</p> |
