Abstract: A retroreflector consists of a support surface (12) coated with a layer (11) of small retroreflecting particles such as glass spheres. The support surface comprises a plurality of regularly repeating, like structural elements (13) which are inclined to the overall plane of the retroreflector. The surface elements (13) can be of various shapes and serve to increase the angular range over which retroreflection can occur. The optical characteristics of the proposed retroreflectors can be tailored so that they are eminently suitable for use in certain beam scanning applications such as continuous monitoring of doorways and windows by an optical beam scanning device located at one corner thereof in order to detect, for example, intruders.

Abstract: Apparatus and method for reading light-dark or color-contrast codes on articles which are displaced over a light-transmitting region of a support of the kind wherein a scanning light beam is directed onto the articles and scattered light reflected from the articles and codes is supplied to a photoelectric transducer the output signal from which is supplied to electronic evaluating means, wherein the scanning light beam is directed upwardly through the light-transmitting region of the support and is displaced along two imaginary straight lines located in the light-transmitting region of the support, said lines, which preferably intersect, extending obliquely to the direction of displacement of the articles and substantially at right angles to one another.

Abstract: 1432924 Seanning system E K SICK [trading as ERWIN SICK OPTIK-ELECTRONIC] 31 July 1974 [15 Sept 1973] 33836/74 Addition to 1388653 Headings G4H and G4M [Also in Division G1] The present invention is a modifidation of the scanning system of Specification 1,388,653), the circular scanning beam 20 of that system being directed to a multi-facetted prism so as to produce a number of scanning ares 20.1, &c., Fig. 4 and Fig. 7. It is stated that the provision of such a prism allows the use of a scanning window 13 of smaller dimensions than would otherwise be needed.
