摘要： A process for monitoring an opening of an enclosed space by an IR alarm system, wherein: a measuring process is generated whereby a modulated IR beam is emitted by at least one IR emitting element of an optoelectronic unit in the form of a pulse and the beam reflected from marginal areas of the opening is detected as a measurement signal by at least one IR receiving element of the optoelectronic unit, with the directional characteristic of th IR beam being matched, by optical components in the path of the beam, to the opening being monitored; the measurement signal detected by the receiving element is compared with a mean value of the previous measurement signals, and a normal operating mode of the alarm system is initiated if there is an approximate correlation between the measurement signal and the mean value, or an alarm operating mode of the alarm system is initiated if there is a significant deviation between the measurement signal and the mean value; in the normal operating mode, the next measuring process is generated after a pause in time, during which the control unit, emitting element and receiving element are switched off; and, in the alarm operating mode, a number of measuring processes are generated in immediate succession and compared with criteria stored in the control module, and an alarm signal is tripped if the measurement signals from the measuring processes correspond with the stored criteria.

摘要： An optical system with an optical unit consisting of a transmission unit with at least one transmission element for emitting optical radiation, a receiving unit with at least one receiving element for detecting optical radiation and an optical path for transmitting the optical radiation between transmission unit and receiving unit. At least one optical unit is located in the optical path to bundle and deflect the optical radiation and an optical body/optical bodies is/are assigned to either the transmission unit or the receiving unit. The optical bodies are designed as a kind of Fresnel lens and have an unstructured surface side and a structured surface side having indentations with steep flanks large slope angle and a small prism angle. The structured surface side of the optical body with indentations forms a first boundary surface for total reflection and a second boundary surface for refracting the optical radiation emitted from the transmission unit or the optical radiation detected by the receiving unit and is turned away from either the transmission unit or the receiving unit.
