    Abstract: A method of measuring light levels, particularly the measurement of exterior light levels in the zone of approach to a tunnel in which vehicles are moving, and from which exterior light levels the minimum light level to be programed inside the tunnel can be calculated, by means of a photo-sensitive cell installed in a recessed tube in order to sense light levels contained within a cone defined by the center of the cell, which constitutes the apex of the cone, and by at least the open end of the tube. The method includes limiting the quantity of light rays entering into tube via the cone, and a device is provided for implementing the method.

    Abstract: An evaluation circuit for use with electronic system which utilizes a plurality of individual transmitters of light, a like plurality of individual receivers of light, and a like plurality of light conducting paths. Each transmitter is connected to its corresponding receiver by a corresponding path so that the light emitted by any transmitter can only impinge upon the corresponding receiver. The light emitted is in the form of pulses. The transmitters are selectively actuated and deactuated in selected format by a multiplexer. The corresponding receivers are synchronized to respond in the same format by a demultiplexer whereby when the system functions properly each receiver will receive and respond only to the light pulse emitted by the corresponding transmitter. In the circuit, a measuring operation is initiated in which each transmitter-receiver pair is individually actuated in a selected sequence. A first channel produces a first signal when each receiver has properly received a light pulse emitted by its corresponding transmitter, the first signal suddenly changing value whenever a receiver fails to receive a light pulse emitted by its corresponding transmitter.

    Abstract: The invention relates to a selective detector arrangement for the detecting of approximately point-like collected light in a predetermined wavelength region and angle of the field of vision, with an optical collector system which is made from a material passing the light at a predetermined wavelength range and with a light sensitive sensor element. The essence of the invention resides in that within a predetermined wavelength range for the optical collector system there is a characteristic focal point surface, which is spaced from the focal point surfaces characteristic of wavelengths lying outside of such range and that the sensor element is coupled with the optical collector system in optical fashion over an aperture which is formed in the focal point surface associated with the predetermined wavelength range, and wherein the size of the aperture substantially corresponds in size to the size of the focal point surface of the light falling at the predetermined angle of the field of vision and in the predetermined wavelength range.
