ABSTRACT:
An elevator display system employs an optical fiber 10 for transmitting power pulses and/or image display information between devices at an elevator boarding site and a control panel installed in a machine room via a modulated laser. At the boarding site the beam is deflected in an X, Y scanning mode and passed onto a half-mirror beam splitter 14. One portion exiting the mirror is directed to a viewing screen 6 to display the desired image, while another portion is converted to a power supply signal by an electrooptical transducer 15 for driving the display deflection circuits, thereby eliminating the need for electrical wiring between the control panel and the boarding site.
