1. Virtual 3D display apparatus comprising:
a display zone, in which a virtual 3D image is to be displayed;
an optical fiber assembly including an input, an output positioned in the display zone, and a plurality of optical fibers each having an input end arranged at the input of the optical fiber assembly for entrance of light and an output end arranged at the output of the optical fiber assembly;
a prime mover for driving the optical fiber assembly in motion;
a plurality of light sources provided at the input of the optical fiber assembly, with each light source at the input end of a respective optical fiber for generating a respective light signal that enters and travels along the optical fiber and is then emitted at the output end thereof, with the emitted light signals together forming a virtual 3D image in the display zone upon motion of the optical fiber assembly by the prime mover; and
a plurality of control elements including at least one light sensor provided at the input of the optical fiber assembly, each for operation to make adjustment of a said virtual 3D image based on a control signal that travels along the respective optical fiber, with the adjustment to be made to a part of a said virtual 3D image associated with the same optical fiber;
wherein the light sensor is for sensing ambient light at the output end of the respective optical fiber, the ambient light acting as a said control signal and travelling from the output end along the optical fiber to the light sensor.
