Abstract (en)
[origin: EP0801369A1] The signal source has a light source positioned at the focus of a rear reflector fitted with a front cover disc. The reflector is shaped so that the output light beam illuminates a measuring screen (20), positioned infront of it in the absence of the front cover disc, over an area (22) with a centre point below the horizontal centre plane (HH) of the screen. The illuminated area is symmetrical relative to the vertical centre plane (VV) of the screen and dips downwards at either side.
