Abstract
A floating image device includes a collimating optical assembly, a light source assembly, an imaging unit, and a microlens array. The light source assembly is suitable for emitting a beam to the collimating optical assembly, the beam is converted into a collimated beam by the collimating optical assembly, and a spread angle of the collimated beam at a half-intensity position is smaller than +/−15°. The imaging unit is arranged on one side of the collimating optical assembly that is away from the light source assembly, and the collimated beam is suitable for being converted into an image beam by the imaging unit in a collimated manner; and the microlens array is arranged on one side of the imaging unit. The microlens array focuses the image beam and projects a focused image beam into a floating image. The floating image device is capable of making the floating image clear.
