Description

Vorrichtung zur Lagebestimmung von Körpern mittels Wärmestrahlen Es ist bereits bekannt, die Lage von Körpern, z. B. Schiffen, mit der Hilfe der von ihnen ausgehenden Wärmestrahlen zu bestimmen. Zu diesem Zwecke verwendet man meist Reflektoren, z. B. Parabolspiegel, in deren Brennpunkten eine auf Temperaturerhöhung ansprechende Vorrichtung, z. B. ein Thermoelement oder ein Bolometer, angeordnet ist. Bei derartigen Einrichtungen treten leicht Schwierigkeiten auf, wenn im Beobachtungsfeld andere Strahlenquellen vorhanden sind. -Um diese Schwierigkeiten zu vermeiden, wird gemäß der Erfindung die Empfangseinrichtung durch einen für Lichtstrahlen undurchlässigen für Wärmestrahlen dagegen durchlässigen Schirm abgedeckt.Device for determining the position of bodies by means of heat rays Es is already known, the location of bodies, e.g. B. Ships, with the help of to determine the heat rays emanating from them. This is mostly used for this purpose Reflectors, e.g. B. parabolic mirrors, in whose focal points a temperature increase appealing device, e.g. B. a thermocouple or a bolometer arranged is. Difficulties are easily encountered with such devices when in the field of observation other radiation sources are present. -To avoid these difficulties, will according to the invention the receiving device by an opaque to light rays on the other hand, a screen permeable to heat radiation is covered.

Bei Verwendung von Parabolspiegeln, in deren Brennpunkten Thermoelemente o. dgl. angeordnet sind, kann man beispielsweise den gesamten Spiegel durch einen Schirm aus geeignetem Material, beispielsweise Hartgummi, abdecken. In diesem Falle wird neben der Ausschaltung unerwünschter Strahlen auch noch ein mechanischer Schutz der empfindlichen Thermoelemente, Bolometer usw. sowie der spiegelnden Fläche erreicht. Unter Umständen kann es jedoch auch vorteilhaft sein, nicht den Spiegel, sondern das Thermoelement bzw. die ihm äquivalente Einrichtung durch einen geeigneten Schirm abzudecken. Man kann beispielsweise das Thermoelement in eine aus Hartgummi bestehende Hohlkugel einschließen.When using parabolic mirrors with thermocouples in their focal points O. The like. Are arranged, you can, for example, the entire mirror by one Cover the screen made of a suitable material, for example hard rubber. In this case In addition to the elimination of unwanted radiation, there is also mechanical protection the sensitive thermocouples, bolometers etc. as well as the reflective surface. Under certain circumstances, however, it can also be advantageous not to use the mirror, but rather the thermocouple or its equivalent by a suitable screen to cover. For example, the thermocouple can be made of hard rubber Include hollow sphere.
