The aim of the work was to study the effect of methylsilica additions and deuterochloroform hydrophobic medium on the water state in a phytocomposite system “Lymphosilica”. The water state in a Lymphosilica composite material, created by mechanochemical activation of a mixture of milled medicinal plants and wetting-drying silica A-300 was studied by low-temperature 1H NMR spectroscopy. The parameters of bound water layers in the initial composite and hydrated mixtures with methylsilica in air and hydrophobic media were measured. It was shown that liquid and solid hydrophobic agents reduced the water binding with the cellulose components of medicinal plants. This can be used to control desorption rate of the bioactive complex for oral and transdermal use such herbal biological active components.

A microprocessor controlled photo-thermoplastic device has been developed for the real-time recording of holographic filters in a hybrid digital-optical data processing system. It is possible to position the filters with an accuracy of 0,2 µm.© (1981) COPYRIGHT SPIE--The International Society for Optical Engineering.

In spite of the dramatic changes in feature size, die size and defect density, wafer inspection continues to be done manually. However, fast automatic wafer inspection will be a key element for efficient submicron VLSI-process technologies. A new two-step laser scanning procedure is described, resulting in processing speeds of up to 40 million pixels per second and spatial resolution down to 0.1 μm.

Die Korrelation stellt ein allgemeingultiges Konzept fur die Klassifizierung von Mustern dar. Mit analogen oder digitalen koharenten optischen Filterungsmethoden konnen Objektmuster erkannt werden. Im Falle des Spatial Filtering nach Van-der-Lugt [1] wird fur jedes Muster ein angepastes Filter benotigt. Daraus resultiert bei grosen Mustervielfalten fur die optischen Filterungsmethoden eine grose Filterzahl. Um diesen Nachteil zu vermeiden, wurden Methoden zur Erzeugung analoger und digitaler Komponentenfilter entwickelt, die einer Reihe von Objektmustern angepast sind. Dadurch wird der Merkmalraum in Unterraume mit vorgegebenem semantischen Inhalt aufgeteilt.

With optically generated component filters a binary recognition of 2-D objects is possible. The correlation signals of the filters are processed by a digital computer system to achieve a classification by signal intensity and shape. The computer also controlls the filtergeneration and carries out the recognition.© (1981) COPYRIGHT SPIE--The International Society for Optical Engineering.
