Abstract
A aerial display system comprising inexpensive optical elements and a high brighted LCD display or similar video image display types provides floating images in an inexpensive enclosure. In the aerial display system, either an anti-reflective acrylic plastic layer or a circular polarizer is disposed proximate and parallel to a beam splitter so that the focal point of the floating image is proximate to the plastic layer or polarizer. This image position yields both a wider field of view and wider perceived field of view.
Claims30
A aerial display device comprising:
- An enclosure having a lower portion, a back panel and a top frame;
- Optical elements including a beam splitter in optical alignment with a spherical mirror and an anti-reflective acrylic plastic to stop reflections from reaching said mirror;
- said beam splitter and said anti-reflective acrylic plastic positioned in a recess of said enclosure and retained therein by said top frame;
- A video source;
- and
- A display device coupled to video source for displaying video images received from said video source, said display device positioned in said lower portion of said enclosure and in optical alignment with said optical elements such that an aerial display of said video images is displayed.
