Abstract

A display system comprises a cathode ray tube (10) including an electron gun (12) for producing a modulated beam of electrons and means (14, 15) for focusing the beam of electrons and scanning it along a strip (17) of phosphor to produce a linear display. Optical scanning means comprising a first vibrating mirror (26) and a second mirror (30) mounted parallel to the first mirror (26) between which an image of the linear display may be reflected several times, is provided to enable viewing of successive images of the linear display in axially aligned juxtaposed relationship, to produce a two dimensional display.
