Abstract: A three-dimensional imaging system and method are provided. The three-dimensional imaging system includes a suspension force field generator, a projection module, and a controller. The suspension force field generator generates a suspension force field to suspend a plurality of scattering particles used for scattering incident light and distribute the scattering particles on a projection plane. The projection module projects an image on the projection plane. The controller is coupled to the suspension force field generator and the projection module, controls the suspension force field generator to change the suspension force field so that the projection plane where the scattering particles are distributed moves in a display space, extracts a slice plane image that matches a position of the projection plane from multiple slice plane images sliced from a three-dimensional stereoscopic image, and controls the projection module to project the extracted slice plane image to the projection plane.

Abstract: An information display method and an information display system are provided. The information display method includes: capturing a background image of an information display area of the transparent display; using critical contrast values and color levels of the background image to calculate a display threshold; using the color levels of the background image and color levels of display information to calculate a recognition evaluation score; and determining whether the recognition evaluation score is greater than or equal to the display threshold. If the recognition evaluation score is greater than or equal to the display threshold, the display information is displayed in the information display area. If the recognition evaluation score is less than the display threshold, an optimized display parameter is calculated by using the display threshold, and optimized display information is displayed in the information display area of the transparent display.

Abstract: A floating image display device, configured to generate a floating image, is provided. The floating image display device includes an image module and at least one transflective optical element. The image module is configured to provide a first image. The transflective optical element includes a first reflective surface and a second reflective surface. The first image is located between the first reflective surface and the second reflective surface. Each of the first reflective surface and the second reflective surface includes a curved surface and has no opening on an optical axis thereof. The second reflective surface is a transflective surface. The first reflective surface and the second reflective surface are configured to re-converge rays from the first image to form a second image. The second image is a floating image.
