Abstract

A display device comprises a chamber having substantially opaque walls and a window located in one wall, the window consisting of a Fresnel lens, such that light from an illuminated object placed in the chamber will be projected out through the Fresnel lens along the optical axis of the lens to form a real image suspended in free space. A plurality of substantially point light sources are provided in the chamber located adjacent the Fresnel lens and spaced around the optical axis of the Fresnel lens, the point light sources being arranged such that in use each provides light which shines through the Fresnel lens towards said real image and which appears as a plurality of substantially point light sources lying along a radial path towards the optical axis of the Fresnel lens when viewed from the direction of said real image. The light sources may be flashed in a random or predetermined sequence to enhance the 'starburst' or 'tunnel' effect which leads the eye to the object being displayed.
