Abstract: FIELD: quantum electronics.  
     SUBSTANCE: invention relates to the field of quantum electronics, namely non-destructive testing and diagnostics by optical methods, and can be used to study the processes of high-temperature combustion of metal powders or their mixtures, as well as the processes of interaction of laser radiation with matter. In the claimed device, the surface of the object of study is illuminated by the radiation of two brightness amplifiers on copper bromide pairs operating synchronously with an adjustable delay relative to each other. In this case, the delay is set in such a way that the radiation of one brightness amplifier does not affect the gain of the other. The operation of the two brightness amplifiers is synchronized by regulating the switching moments of the two thyratrons in the excitation circuits, which are set by changing the arrival time of the trigger pulses on the thyratron grids by changing the inductances of the ferromagnetic variometers, which is provided by smoothly moving the ferromagnetic cores inside the inductors. The use of two image acquisition channels makes it possible to explore two areas of the object of study almost simultaneously within the exposure time of digital cameras.  
     EFFECT: possibility of simultaneous observation of powder combustion with different magnification and spatial resolution in one area of the object of study, within one inter-pulse interval of the brightness amplifier, and the possibility of simultaneous observation of burning in two areas of the object of study within one inter-pulse interval of the brightness amplifier.

Next, the line-of-sight vector is normalized and the angle of rotation in the horizontal plane relatively to the design axis of the aircraft is calculated. Then the line-of-sight vector is projected into the coordinate system associated with the OES, where turns are made sequentially along the elevation angle and the azimuth angle. At the last stage of processing, the coordinates of the ground (above-water) object of interest are calculated using the coordinates of the aircraft, altitude, adjustment coefficients, and the calculated length of the line-of-sight vector.

Abstract: Die vorliegende Erfindung bezieht sich auf eine brennstoffbeheizte Wärmequelle mit Haupt- und Zündbrenner sowie einem im Zuge einer Luftzufuhr- beziehungsweise Abgasabfuhrleitung liegenden Gebläse zur Zwangsentlüftung des Feuerungsraumes der Wärmequelle. Wird bei einer solchen Wärmequelle keine Wärme angefordert, steht das Gebläse, während der Zündgassbrenner weiter brennt. Bei ungünstigen Betriebsverhältnissen kann es hier zu einer Überhitzung des Feuerungsraums und des Wärmetauschers kommen, der den Feuerungsraum durchsetzt. Zur Vermeidung dieser Überhitzung ist im Feuerungsraum ein Temperaturfühler vorgesehen, der bei Überschreiten einer eingestellten Grenztemperatur für ein kurzfristiges Anspringen des Gebläsemotors sorgt.
