Figure 1 illustrates a compact modular housing 30 which contains the components used to form an output image at a recording medium. A laser 32 generates a collimated beam of monochromatic light. The monochromatic light beam is reflected by first mirror 34 onto modulator 36, the light beam being modulated in conformance with the information contained in a video signal. Modulator 36 may be any suitable acousto-optic or electro-optical modulator for recording the video information in the form of a modulated light beam at the output of the modulator. By means of the modulator the information within the video signal is represented by the modulated light beam 38. Light beam 38 is reflected by second mirror 40 and is incident on imaging lens 41. Imaging lens 41 produces a beam 42 which is reflected by third and fourth mirrors 44 and 46, and impinges upon a plurality of contiguous facets of scanning polygon 48, as shown.
