Description
Verfahren zur Herstellung akustisch-optischer Bildwandler Die Erfindung bezieht sich auf ein Verfahren zur T-lerstellung akustisch-optischer Bildlvandler, bei welchen der Farbumschlag gewisser Stoffe bei spezifischen Temperaturen zur sichtbaren Darstellung der Intensitätsverteilung in Ultraschallfeldern benutzt wird.Process for the production of acoustic-optical image converters The invention relates to a process for creating acousto-optical image converter, in which the color change of certain substances becomes visible at specific temperatures Representation of the intensity distribution in ultrasonic fields is used.
Nach der Erfindung wird der Farbumschlag dadurch beschleunigt, daß die in ihrer Farbe wärmeempfindliehen Stoffe mit solchen Stoffen in Verbindung gebracht werden die eine hohe Ultraschallabsorption aufweisen. So kann man die wärmeempfindlichen Stoffe beispielsweise in Flüssigkeiten aufschwemmen oder in eine erstarrende Schicht, wie z. B. Lack, Wachs, Kunstharz und ähnliches, einbetten, die wie Benzol eine hohe Absorption für Ultraschall zeigen. Diese durch das etreffende Dispersionsmittel gegebene Absorption kallll weiterhin noch dadurch erhöht werden, daß nian in das Dispersionsmittel feste Teilchen, z. B. According to the invention, the color change is accelerated in that the substances that are heat-sensitive in their color are associated with such substances will have high ultrasound absorption. So you can get the heat sensitive Suspend substances, for example, in liquids or in a solidifying layer, such as B. varnish, wax, synthetic resin and the like, which, like benzene, have a high Show absorption for ultrasound. This through the appropriate dispersant given absorption can be further increased by the fact that nian in the Dispersant solid particles, e.g. B.
Glaskugeln, Quarzsand od. dgl., einbringt. Derartige Zusätze bringen weiterhin noch den Vorteil, daß sie die thermische Diffusion innerhalb des Dispersionsmittels verzögern und damit den Farbenausgleich parallel zur Oberfläche und eine Vermischung der Bildkonturen verlangsamen.Glass balls, quartz sand or the like. Bring such additives still have the advantage that they reduce thermal diffusion within the dispersant delay and thus the color balance parallel to the surface and a mixing slow down the contours of the image.
Ein weiterer Vorteil, der die Empfindlichkeit des Verfahrens steigert. wird dadurch gewonnen, daß als Dispersionsmittel und gegebenenfalls als Dispersa solche Stoffe gewählt werden, die eine niedrige spezifische Wärme aufweisen. Hierdurch erzielt man bei gleicher Ultraschallenergie eine möglichst große Temperaturerhöhung. Another advantage that increases the sensitivity of the procedure. is obtained in that as a dispersant and optionally as a Dispersa those substances are chosen that have a low specific heat. Through this the greatest possible temperature increase is achieved with the same ultrasonic energy.
