<p>Three-dimensional imaging system employs a light beam deflected over a two-dimensional deflecting surface on a screen rotating about an axis which coincides with the optical axis of the deflecting surface, whereby the screen represent the geometrical generatrix of an image space. The surface elements of the screen (3) are arranged at an angle to the axis of rotation (2). Pref. the screen is in the form of a single lead screw whose axis coincides with the axis of rotation. The screen is housed in a cylindrical casing (5) of air-tight material which is transparent in the section facing the observer.</p> |
