Description
Verfahren zur Erzeugung thermi3cher Bilder Zusatz zu Patent (Anmeldung P 25 18 937.1) Die IIauptarimeldung betrifft ein Verfahren zur Erzeugung und Wiedergabe thermograiischer Bilder, insbesondere von Bildern von Gegenständen mit stark von einander abweichenden Tempersturen, sowie ein Gerät zur DurchfWirung dieses Verfahrens. Process for generating thermal images Addition to patent (registration P 25 18 937.1) The main message relates to a method for generation and reproduction thermographic images, in particular images of objects with strong of different temperatures, as well as a device to carry out this process.
Bei dem Verfahren werden mehrere Raster verschiedcner Feinheit Ubereinander geschoben, so daß mit dem gröberen Raster Gegenstände größerer Ausdehnung aber kleiner Temperatur-Differenz wiedergegeben und mit dcm feineren Raster Gegeneta stünde geringerer räunilicher Ausdehnung aber großer Temperatur-Differenz angezeigt werden. hierbei ist es zweckmäßig, die Bild-Erzeugung und -Wiedorgabe so einzustellen,daß ein verhältnismäßig grobes Raster mit einem sehr feinen Raster kombiniert wird.In the process, several grids of different degrees of fineness are superimposed on one another pushed, so that with the coarser grid objects of larger dimensions but smaller Temperature difference shown and with the finer grid countereta would be lower Räunilicher expansion but large temperature difference are displayed. here it is advisable to set the image generation and playback so that a relatively coarse grid is combined with a very fine grid.
Bei der praktischen Durchführung verwendet man heute fast ausschließlich ein Zeilenabtast-Verfahren, wobei meist nicht eine Zeile, sondern eine ganze Zeilengruppe gleichzeitig abgetastet wird. Bei der den Gegenstand der Hauptanmeldung bildenden Erfindung wird das Bildraster mit einer Doppel-Zellengruppe erzeugt. Die optische Durchftlhrung des Verfahrens erfordert indessen einen ziemlichen technischen Aufwand.In practice, it is used almost exclusively today a line scan method, with mostly not a line, but a whole group of lines is scanned at the same time. In the case of the subject of the main application Invention, the image grid is generated with a double cell group. The optical one Carrying out the process, however, requires a considerable amount of technical effort.
Durch die vorliegende Erfindung soll das Verfahren nach Patent (Anmeldung P 25 18 937.1) dahingehend vervollkommnet werden, daß ein Obereinander-Schreiben beider Raster in einfacher speise möglich wird.The present invention is intended to use the method according to the patent (application P 25 18 937.1) to the effect that writing on top of one another both grids in simple food becomes possible.
Beim erfindungsgemäßen Verfahren wird ein normales Abtast-Verfahren mit einem elektrischen Verfahren kombiniert, das aus den abgetasteten Werten auf elektrischem Wege ein Doppel-Raster erzeugt.In the method according to the invention, a normal scanning method is used combined with an electrical method, which is based on the sampled values electrical path creates a double grid.
Bei diesem elektrischen Verfahren werden Jeweils mehrere Zellen zu einer Gruppe zusammengefaßt und die Signale der Zellen jeder Gruppe einmal parallel und einmal einzeln verarbeitet. Beim Parallel-Schalten addieren sich die von den einzelnen Zellen aufgenommenen Werte zu einem Gruppenwert; daraus ergibt sich ein grobes Raster. Bei Einzel-Schaltung werden dagegen die von den einzelnen Zellen aufgenommenen Werte auch einzeln weitergegeben, und auf diese Weise erhält man eine größere Zahl eng nebeneinander stehender Werte,die gemeinsam ein Peinraster ergeben.In this electrical process, several cells are closed at a time a group combined and the signals of the cells of each group once in parallel and processed once individually. When switching in parallel, those of the add up values recorded in individual cells to form a group value; this results in a rough grid. In the case of individual switching, on the other hand, those of the individual cells are used The recorded values are also passed on individually, and in this way you get a larger number of closely spaced values that together result in a pain grid.
Die Anordnung der Zellen und die dazugehörige Schaltung sind in den beiliegenden Figuren für ein einfaches Beispiel dargestellt. Es zeigen: Fig.1 die Anordnung zweier Gruppen von Je vier Zellen und ihre Zusammenfassung zu Je einer Abtast-Einheit; Fig.2 ein Schaltbild für zwei Abtast-Eiiiheiten gemäß Fig.1.The arrangement of the cells and the associated circuitry are shown in accompanying figures for a simple example. They show: FIG. 1 the Arrangement of two groups of four cells each and their combination into one each Scanning unit; FIG. 2 is a circuit diagram for two scanning units according to FIG.
Vier Zellen, 1,2,3,4, sind zu einer Abtast-Einheit 10, vier weitere Abtast-Zellen, 1'2',3',4', zu einer zweiten Abtast-Einheit 10' zusammengefaßt. hierbei liegen die Abtast-Zellen 1 und 2 auf einer Zeile und die Abtast-Bellen 3 und 4 auf der nächsten Abtast-Zeile. Ebenso liegen die Zellen 1' und 2' auf einer Abtast-Zeile und die Zellen 3' und 4' auf der nächsten Abtast-Zeile. Wenn die Abtast-Einheit eines Rasters aus den vier Abtast-Zellen wie angegeben besteht, so wird das Grob-Raster elektrisch durch Parallel-Schaltung aller vier Zellen erzeugt, während das Feinraster durch Serien-Abtastung der Zellen 1 und 2 bzw. 3 und 4 und Zusammenfassen der beiden Paare erzeugt wird. Dieses Raster ist flächengeometrisch um den Faktor 4 feiner. Das Gleiche gilt natürlich auch für eine Gruppe 3 x 3 « 4 x 4 usw.Four cells, 1, 2, 3, 4, are to a scanning unit 10, four more Scanning cells, 1'2 ', 3', 4 ', combined to form a second scanning unit 10'. here scan cells 1 and 2 are on one line and scan cells 3 and 4 are on one line the next scan line. Likewise, cells 1 'and 2' are on one scan line and cells 3 'and 4' on the next scan line. When the scanning unit If a grid consists of the four sample cells as indicated, then the coarse grid becomes electrically generated by connecting all four cells in parallel, while the fine grid by serial scanning of cells 1 and 2 or 3 and 4 and combining the two Pairs is generated. In terms of area geometry, this grid is finer by a factor of 4. The same applies of course to a group of 3 x 3 «4 x 4, etc.

Zellenveratärker 1 ist über ein iiaufzeitglied 8, dessen Laufzeit gleich der Abtastzeit-Differenz eines Objekt-Bildpunktes zwischen den Zeilen 1 und 2 ist, mit Leitung 11 verbunden. Zellenverstärker 2 ist mit Leitung 12 verbunden. Die Leitungen 11 und 12 speisen den Additions-Verstärker 6 zur Gewinnung des Serien-Abtastsignals 16 von Zeile 1 des Feinrasters. Entsprechend arbeiten die Einzelverstärker 9 und 4 mit Additions-Verstärker 7 zur Gewinnung von Serien-Abtastsignal 17 für Zeile 2 des Lpeinrasterz. Das Grobraster-Signal 15 wird aus der Summe der Zellenverstirker-Signale 1, 2, 3, 4 über die Leitungen 21, 22, 23 und 24 mit Hilfe des Additions-Verstärkers 5 gewonnen.In Fig. 2 the individual amplifiers of the cells with 1 to 4 or 1 ' bi3 4 '. Zellveratärker 1 is via an iiaaufzeitelement 8, whose running time equal to the scanning time difference of an object pixel between lines 1 and 2 is connected to line 11. Cell repeater 2 is connected to line 12. The lines 11 and 12 feed the addition amplifier 6 for obtaining the serial sampling signal 16 of line 1 of the fine grid. The individual amplifiers 9 and 9 work accordingly 4 with addition amplifier 7 for obtaining serial scanning signal 17 for line 2 of the Lpeinrasterz. The coarse raster signal 15 is the sum of the cell amplifier signals 1, 2, 3, 4 via lines 21, 22, 23 and 24 using the addition amplifier 5 won.
In gleicher cise sind die Zellen 1' und 2' einerseits mit dem Addition-Verstärker 6', andererseits mit dem Additions-Verstärker 5' verbunden und die Zellen 3' und 4' mit dem Additions-Verstärker 7' und dem Additions-Verstärker 5'. Von den Verstärkern gelangen die Signale über die Leitungen 15, 16, 17 und 15', 16', 17' in die Auswerte-Elektronik.In the same cise, cells 1 'and 2' are on the one hand with the addition amplifier 6 ', on the other hand connected to the addition amplifier 5' and the cells 3 'and 4 'with the addition amplifier 7' and the addition amplifier 5 '. From the amplifiers the signals reach the evaluation electronics via lines 15, 16, 17 and 15 ', 16', 17 '.
