LIGHT-DEFLECTION THREE-DIMENSIONAL IMAGING DEVICE AND PROJECTION DEVICE, AND APPLICATION THEREOF

摘要

A light-deflection three-dimensional imaging device and a projection device (10), and the application thereof. The light-deflection three-dimensional imaging device comprises a projection device (10), a receiving device (20) and a processor (30). The projection device (10) comprises a light source (11), a grating (12), a condensing lens group (13), a light deflection element (15) and an emission lens (14), wherein after the modulation by the grating (12), the aggregation by the condensing lens group (13) and the deflection by the light deflection element (15), the projection light transmitted by the light source (11) penetrates the emission lens (14) and is emitted from a side surface of the projection device (10). The light deflection element (15) is provided to change a projection path of light emitted from the light source (11), thereby changing an installation manner of the projection device (10), so that the thickness thereof is significantly reduced, thereby facilitating the installation in lighter and thinner electronic mobile devices, such as a mobile phone, a laptop, a tablet computer, etc.
