Abstract
An optical sensor (10), such as an infrared sensor for detecting overheated wheels or wheel bearing on trains passing along a section of track, comprises an optical system (24) having its receiving optical axis angled (e.g. perpendicularly) to the line of sight of the sensor through a sighting aperture (26). A mirror (30) is pivotally mounted in the line of sight and is movable between a first (operating) position in which it reflects rays travelling along the line of sight to the optical system (24), and a second (aiming) position in which an observer can look through a viewing aperture in the top of the sensor and see through the sighting aperture (26) via the mirror (30). When cross hairs (36) between the viewing aperture and the mirror (30) appear superimposed on cross hairs (38) between the mirror (30) and the sighting aperture (26), the observers' line of sight through the aperture (26) is the same as that of the optical system (24) when the mirror is in the first position, thus permitting the sensor to be aimed accurately and easily at a target. <IMAGE>
