Title:
SCATTERING PROJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/148988
Kind Code:
A1
Abstract:
A scattering projection device, comprising a scattering medium (1), a light source combination (3) and a synchronous control system (4), wherein the scattering medium (1) is a solid, liquid or gas medium capable of forming a scattering effect on passing light beams; the light source combination (3) is a group of light sources projected on the scattering medium (1) from different directions; light beams of the light source combination (3) are concentrated on one point of the scattering medium (1) and superposed to generate a brightness and color differential with other points so as to form a holographic display effect; the synchronous control system (4) is used for controlling the brightness, focal length, projection direction and time synchronization of the light source combination (3).
