Abstract
1512152 Multiple reflection arrangements ERWIN SICK GmbH OPTIK-ELEKTRONIK 26 Feb 1976 [28 Feb 1975] 07640/76 Heading G2J In an apparatus wherein a beam of light traverses a measuring path, a light source 12 (which may be formed by illuminating a slit) is placed at the focus of a lens 13 so that collimated light falls on a retro reflector 14. In the absence of optical wedge 18 (or wedges 18, 18′) the light would be reimaged at the slit. The wedge (or wedges) cause reimaging at 12′, and a further retroreflector 16 returns the light to lens 13, the light beam finally passing back through the slit 12 to be reflected to a detector 41 after four passes. Other embodiments having a larger number of passes are described. A particular embodiment is described with reference to Figs. 9-10 (not shown).
