Abstract

The subject matter of the invention permits novel methods for determining the internal consistence of liquid and solid substances of variable depth at wavelengths of visible light and regions adjacent thereto. Said subject matter thereby permits biological and technical materials to be transirradiated without simultaneous risk due to harmful radiation loads. In addition, due to pulsing of the radiation, longer ranges are achieved than with comparable wavelengths. By contrast with previous methods, the use of the subject matter of the invention is substantially more cost-effective and more efficient.

Description

Zielsetzung der vorliegenden Erfindung ist die Erzeugung von Intensitätsdarstellungen des durchdrungenen Objektes zur Ermittlung der Konsistenz flüssiger und fester Stoffe unter Vermeidung schädlicher Nebenwirkungen durch die Eigenschaften des Strahles selbst.The aim of the present invention is the generation of intensity representations of the penetrated object to determine the consistency of liquid and solid substances while avoiding harmful side effects from the Properties of the beam itself.

Mit den hier zur Anwendung kommenden Wellenlängen ist es bisher nicht möglich gewesen, den Körper zu durchdringen. Erst die Erzeugung von Pulsfolgen mit Subnano- bzw. Subpicosekunden Dauer ermöglicht die Durchdringung von Stoffen mit diesen Wellenlängen.With the wavelengths used here it is have not been able to penetrate the body. Only the generation of pulse sequences with subnano or subpicoseconds Duration allows the penetration of fabrics with these wavelengths.

Erreicht wird bei der vorliegenden Erfindung die Durchdringung durch Verwendung eines modulierten Strahls durch Erzeugung von Pulsfolgen im Subnano- und Sugpicobereich. Der Strahl wird senkrecht oder unter einem bestimmten Winkel auf die Oberfläche des zu durchdringenden Objektes gelenkt. Auf der Austrittsseite erfaßt ein entsprechend schneller Empfänger, z. B. eine Strobe-Kamera, die Intensität der Durchgangsstrahlung. Dieser Empfänger kann auch auf der gleichen Seite des Objektes wie der Sender angebracht sein. In diesem Fall wird die einmal durchdrungene Strahlung durch eine geeignete Reflektionsvorrichtung zurückgeworfen. Dieser Vorgang kann bei Bedarf einmal oder mehrfach wiederholt werden. Zur Erfassung von Stoffzusammensetzungen bis zu einer bestimmten Tiefe wird durch Schaffung von künstlichen Inhomogenitäten, z. B. durch ein Ultraschallgitter, das Impulsecho in entsprechender Position im Stoff generiert.The penetration is achieved in the present invention by using a modulated beam Generation of pulse trains in the subnano and sugpico range. The beam becomes vertical or below a certain one Angle on the surface of the object to be penetrated directed. On the exit side, an entered accordingly faster receiver, e.g. B. a strobe camera, the intensity the through radiation. This recipient can too attached to the same side of the object as the transmitter be. In this case the one that is once penetrated  Radiation through a suitable reflection device thrown back. This process can be done once if necessary or repeated several times. To capture Compositions of substances to a certain depth is created by creating artificial inhomogeneities, e.g. B. by an ultrasonic grid, the pulse echo in corresponding position in the fabric generated.

Resultat des Vorganges ist eine bildhafte oder nicht- bildhafte Intensitätsdarstellung der vom Strahl durchdrungenen Stoffe unterschiedlicher optischer Eigenschaften.The result of the process is a pictorial or non- pictorial intensity representation of the penetrated by the beam Fabrics with different optical properties.

Die zeichnerische Darstellung zeigt in Abb. 1 den Erfindungsgegenstand mit dem Sender auf der Vorder- und den Empfänger auf der Rückseite des Objektes.The drawing shows in Fig. 1 the subject of the invention with the transmitter on the front and the receiver on the back of the object.
