Abstract
An imaging device that is capable of causing a change in an aerial image, and can be reduced in size is provided. The imaging device includes, in a housing, a disk-shaped retro-reflection sheet in which a plurality of designs are formed at different positions, an LED light source configured to irradiate the retro-reflection sheet, a beam splitter, and a motor configured to rotate and move the retro-reflection sheet. The retro-reflection sheet is rotated and moved to enable switching of aerial images of the designs irradiated by the LED light source.
Claims9
An imaging device capable of displaying an aerial image by utilizing retro-reflection, the imaging device comprising:
- a retro-reflection member in which a design including a cutout or an opening is formed;
- a light source configured to irradiate the retro-reflection member from a back surface side;
- an optical member that is situated above the retro-reflection member and through which retro-reflected light can be transmitted;
- and
- a moving member configured to move the retro-reflection member,
- wherein the imaging device causes a change in an aerial image of the design when the retro-reflection member is moved.
