摘要： A spectroanalytical gas measuring apparatus has a radiation source (36), a transmitting condensor (19), an objective (13) and a beam divider (11) which deflects at least a part of the radiation reflected back to the apparatus by a reflector (40) to a polychromator or spectrometer (32). The transmitted radiation falls after the beam divider (11) onto a deflecting mirror (12) which is adjustable between two positions and which directs the light to an objective reflector (13). The objective reflector (13) reflects the radiation to a follow-up mirror (15) arranged opposite to the beam passage opening (14). At least one long and one short focal length objective reflector (13) are provided in order to ensure different ranges of distance in conjunction with the adjustable deflecting mirror (12).

摘要： A light grid arrangement features a row of light emitting diodes 0 to 9 which are periodically switched on one after the other by a ring counter 11 and are arranged to direct their light through a monitoring region 23 towards an image forming optical means which is conveniently in the form of a concave mirror 24. The light beams are concentrated by the concave mirror 24 onto a photodetector 18 arranged behind a slot aperture 25 located at the focal point of the concave mirror. Missing pulses from the photodetector are detected by processing circuitry 26 to indicate obstruction of the light grid. The width of the slot aperture 25 restricts the width of each individual light beam so that only beams of light from the light emitting diodes that are generally parallel to the axis of the concave mirror are detected. In this way costly optical focussing elements are avoided as are the difficulties of aligning these optical elements with the other optical components of a system. The length of the monitored region can be increased as desired by placing a number of concave mirror and light emitting diode arrangements alongside one another.

摘要： An electrooptical scanning device which can detect the relative position of register mark applied to a moving web, either serially on a single track or in two parallel, side-by-side tracks which extend in the direction of movement of the web. Light from a light source positioned some distance above the web is split into three light beams and the light beams are reflected downwardly towards the web. Lenses are positioned to receive and direct the light beam at an oblique angle onto the marks on the track or tracks. The lenses are aligned with the tracks and the light beam passing through a given lens is directed to the opposite track to illuminate three positions, two on the first track and one position on the second track. Light impinging on the web at these positions is scattered. Vertically upwardly scattered light is captured by the lens overlying the particular illuminated position and hence directed via suitable optics to photo-detectors which generate output signals that can be used to determine the relative locations of the marks to thereby detect any misalignments of the web.

摘要： The light sensor has a light transmitter (10, 12) which radiates the light along an axis (x.sub.0) of a transmitter system and two light receiving systems (12, 14) which pick up the light scattered back from an object (G) to be detected along a receiving system axis (x.sub.1, x.sub.2). A light sensitive element (16) has three detection zones (El.sub.T, E.sub.H, E2.sub.T) arranged in a row of which the outer zones (E1.sub.T and E2.sub.T) each receive light via one of the receiving systems (12, 14) from a sensing zone (T) and of which the central detection zone (E.sub.H) accepts light via both light receiving systems from the background region (H) of the field of view of the light sensor. An output signal which is used for object recognition is obtained by additive superposition of the signals of the detection zones (E1.sub.T, E2.sub.T) associated with the scanning region (T) and by difference formation with the signal from the detection zone (E.sub.H) associated with the background region (H). The sensing distance (TW) is adjusted by adjusting a roof edge mirror (18) arranged in front of the light sensitive element (16).

摘要： An optical electronic distance sensor utilizes a V-light barrier in which a light transmitter 11 transmits a substantially parallel light beam 14 at a defined angle and a light receiver 12 receives a substantially parallel light beam 15 at a defined angle and delivers an electrical output signal dependent on the intensity of the received light beam. The distance of the intersection of the transmitted and received light beam paths, i.e. the apex of the V, from the light transmitter and receiver defines the sensing distance of the light barrier and is adjusted by adjusting the separation of the light transmitter and receiver. For this purpose the light transmitter and receiver are displaceably mounted on a mounting rail. The distance sensor is particularly useful in indoor carparks for determining the presence or absence of a vehicle in a parking space.

摘要： A light barrier system for monitoring the presence or absence of an obstacle in the monitored area and for simultaneously monitoring itself to detect contamination of the system. A photo-converter emits signals indicative of the light intensity of a light barrier beam and the signal is applied to a first, obstacle switch which is normally open but which closes at a relatively high level of darkness, i.e. when an obstacle is present. A converter signal is also applied to a second, contamination switch which is normally open but which closes at a lesser degree of darkness than the first switch so that both switches can be simultaneously closed. The outputs of the switches when closed are applied to relays to switch the relays between alternative position to indicate (a) the presence of an obstacle in the light curtain area and (b) the contamination of the light curtain system irrespective of whether or not an obstacle is present.

摘要： An apparatus is described for generating a light curtain which includes an originally spherical strip-like concave mirror 10 and a light deflecting element 12 arranged in the vicinity of the focal point of the concave mirror. The light deflecting element 12 guides a bundled light beam periodically over the concave mirror 10. The strip-like concave mirror 10 is twisted within itself in such a way that each surface portion of the concave mirror 10 which is illuminated during a complete sweep of the light beam extends at at least substantially the same angle to the beam axis in a plane perpendicular to the scanning direction.
