    Abstract: A sensor device according to the present invention has a detection mode for detecting an object W, a first setting mode for changing the output duration of an output signal, and a second setting mode for changing a light-emission period of light emitted to the object W. These modes are switchable by a mode selector switch 12. If a rotary control knob 15 is operated in the detection mode, a CPU 30 changes a setting of a threshold value in response to the operation of the rotary control knob 15 and displays the changed setting of the threshold value on a digital indicator 20. This makes it possible to accurately change settings through relatively simple operations. The rate of change may correspond to the speed of operation of the knob.

    Abstract: An optical examination apparatus for optically examining density, distribution, etc. of oxygen in an object to be examined such as organic tissue like brain tissue, of man or animal a light source (2); and an optical fibre bundle (6) having one end on which light emitted from the light source (2) is incident and which is divided at the other end into a first (61) and second (62) branch with a predetermined ratio of division; a transmitted and scattered light detection means (3) for detecting light which is emitted from the first branch fibre bundle (61) and, in use, is transmitted through and scattered by an object (1) to be examined; a monitoring light detection means (4) for detecting monitoring light emitted from the second branch fibre bundle (62); and, normalization means (5) for normalizing an output of the transmitted and scattered light detection means (3) on the basis of an output from the monitoring light detection means (4). Representative sampling means 602 Figure 1(b), 64 Figure 2(a)) are included to ensure that the light output from the second branch fibre bundle (62) is representative of that output by the light source (2). The presentative sampling means may be provided by distributing the optical fibres (602) forming the second branch fibre bundle uniformly over the one end of the optical fibre bundle. Alternatively they may comprise a mode scrambler (64) interposed between the one end of the optical fibre bundle and the light source to distribute light from the light source over the whole fibre bundle.

    Abstract: The invention relates to a sensor having a filter arrangement, downstream of which there is arranged a detector arrangement, and an evaluating device connected to the detector arrangement. The filter arrangement has at least a first filter, the suspect filter, and at least one second filter, the reference filter(s). The first filter is configured as a band pass filter allowing the passage of a first predetermined band, the suspect band. The at least one second filter is configured as a band pass filter allowing the passage of a second predetermined band(s), the reference band(s). The detector arrangement has at least one detector associated with at least one of the filters. The band passes reference filters are distributed above and below the band pass of the suspect filter. The sensor with advantage could be utilized within the IR band, and could advantageously be used to detect CO2.
