Area of Science:

Optics
Display Technology
Optical Engineering

Background:

Conventional floating display systems utilizing dihedral corner reflector arrays often suffer from bulky, folded configurations.
This bulkiness limits their practical application and portability.

Purpose of the Study:

To propose and experimentally verify a compact floating display system.
To overcome the size limitations of existing dihedral corner reflector array-based floating displays.

Main Methods:

Implementation of a compact, in-line configuration using a pair of decentered lenses.
Utilizing the decentered lenses to tilt the effective incident angle onto the dihedral corner reflector array.
Ensuring the display panel and reflector array remain parallel while separating ghost images.

Main Results:

Successful demonstration of a compact floating display system.
The decentered lens design effectively reduced system bulk.
Ghost images were successfully separated from the desired floating images through optical refraction.

Conclusions:

The proposed technique enables a compact in-line floating display system.
Decentered lenses are effective in reducing the overall size of dihedral corner reflector array displays.
The method provides a viable solution for creating smaller, more practical floating display devices.
