摘要： An interference object is identified in a scatter volume of an optical fire detector, which operates according to the scattered light principle. To achieve a higher level of interference protection using a simple structure in a compact fire detector, a common scatter volume is used instead of separate scatter volumes.

摘要： A sensor apparatus for optically detecting an object includes (a) a first emitting device, configured to emit a first emission beam, (b) a first receiving device, configured to receive a first reception beam, (c) a second receiving device, configured to receive a second reception beam, and (d) an evaluation unit connected downstream of the first receiving device and the second receiving device. The first reception beam and/or the second reception beam contains scattered light which is produced when an at least partial scattering of the first transmission beam occurs at the object. The evaluation unit is coupled to the first receiving device and the second receiving device so as to receive a difference signal between a first output signal of the first receiving device and a second output signal of the second receiving device. The sensor apparatus may be incorporated in a proximity sensor and a danger warning system.

摘要： A smoke detector, on a base element with a flat installation surface, features a first light transmitter attached to the installation surface for emission of a first illumination light, a first light receiver attached next to the first light transmitter for receiving a first measurement light which results from a backscattering of the first illumination light at a measurement object located in a first detection area. The smoke detector further features a second light transmitter attached to the installation surface for emission of a second object illumination light, a second light receiver attached next to the second light transmitter for receiving a second measurement light which results from a backscattering of the second illumination light at a measurement object located in a second detection area, and a data processing device, which is used for joint evaluation of a first output signal of the first light receiver and of a second output signal of a second light receiver. In addition a method for the detection of smoke using the described smoke detector is specified.

摘要： A device for detecting smoke based on the principle of optical scattered light measurements has a light emitting device, configured to issue a temporal succession of light pulses. A first light pulse has a first spectral distribution and a second light pulse has a second spectral distribution that is different from the first spectral distribution. A light receiver receives a first scattered light from the first light pulse and a second scattered light from the second light pulse, and generates a first output signal that is indicative for the first scattered light, and a second output signals that is indicative for the second scattered light. An evaluation unit compares the first output signal with the second output signal. In a preferred embodiment of the device, the light emitter and the light receiver are arranged directly next to one another.
