Keywords:aerial imaging, retro-reflection

We propose an optical system for two-view aerial signage over an LED panel. A retro-reflective slit array and a beam splitter are placed in front of the LED panel and form the aerial image over the LED panel. The aerial signage shows different apparent images depending on the viewing directions. We confirmed that placing a linear prism in front of the LED panel reduces crosstalk in the aerial image.
