Abstract
This application provides a floating optical device, an optical module, and an optical system that are configured to perform floating display. The floating optical device includes a focusing layer, a transmission layer, and a convergence layer that are sequentially stacked in a direction of an optical axis. The focusing layer includes a plurality of focusing units that are periodically arrayed. The convergence layer includes a plurality of convergence units that are periodically arrayed. The plurality of focusing units and the plurality of convergence units are in a one-to-one correspondence in the direction of the optical axis. In the focusing unit and the convergence unit that correspond to each other, the focusing unit is configured to modulate incident light rays, to concentrate incident light rays that are parallel to each other to a same incident concentration point on the incident surface of the transmission layer.
