To produce first and second light control panels 11, a molded preform 22 made from a transparent resin, which includes triangle-cross-section grooves 15 (each having an inclined surface 14 and a vertical surface 23) and triangle-cross-section protruded strips 16 (formed by the grooves 15 next to each other) respectively arranged in parallel on a front side of a transparent plate material 12, is produced by press-molding, injection-molding, or roll-molding, and mirror surfaces 13 are selectively formed only on the vertical surfaces 23 of the grooves 15. The first and second light control panels 11 each having a group of band-like light-reflective surfaces standing upright and spaced in parallel are overlapped such that the groups of band-like light-reflective surfaces are crossed in a plan view. Thereby providing a stereoscopic-image-forming device and its producing method enabling to easily produce the first and second light control panels 11 and obtain clearer stereoscopic images.

A unique method and a device to generate free space “pop-out” & “sink-in” holograms is disclosed herein. The hologram disclosed herein does not use any special medium, mirrors, reflective screens or wearables such as headgear & special glasses. The hologram disclosed herein can be created in free space, outer space or in air, without any other optical components except for the special display screen of the hologram device. This device demonstrates a free space hologram and the hologram Augmented Reality & hologram Virtual Reality. A camera capable of hologram quality images equipped with a smart lens which mimics the human eye by changing it's lens aperture according to the light intensity as the pupil of the human eye and focus & capture “pop-out” & “sink-in” hologram images is disclosed herein. The audio which is incorporated with the device provide multi dimensional multi directional audio effects.

A device and a method for generating floating images are provided. An optical imaging module generates a first floating image. A sensing module sends a detection signal to sense first position information of a tested object at a first time point, and generates a feedback signal according to the first position information when the first position information is within a contour range of the first floating image. A signal processing module is electrically connected to the optical imaging module and the sensing module to receive the feedback signal and generate at least one control command and/or at least one feedback command corresponding to the feedback signal. The at least one control command is transmitted to a controller to perform corresponding control on the controller, and the at least one feedback command is transmitted to the optical imaging module, so that the optical imaging module generates a second floating image different from the first floating image.
