Abstract
A surveillance detector comprising a light emitter and a light guide which is optically connected to the light emitter, which light guide includes reflectors mounted therein, a special feature being the fact that the light guide is capable of converting the light from the light emitter at least in part into a light beam to be built up in the space to be kept under surveillance, and in that the light guide is capable of guiding light from the light beam that is reflected by an object in the space to be kept under surveillance to a light receiver of the detector, which is optically coupled to the light guide.
