    Opis:
    Ice sheet of the Wartanian Glaciation and their deposits shaped the landscape of the Węgrów Basin. Biogenic lake sediments at Porzewnica and Marysin sites (figs.1, 2) consist of about 5 m thick silts and gyttja, covered by 1.15 m thick sand at Porzewnica and by 8.5 m thick silts and sands at Marysin. In the Porzewnica pollen diagram (fig. 4) there are 7 L PAZ and 1 interzone without sporomorphs. representing vegetation succession during the late Wartanian Glaciation, the protocratic, mesocratic and part of the telocratic phases of the Eemian Interglacial. Spectra of sediments at the Marysin site represent 4 L PAZ of the youngest part of the mesocratic phase and fragments of the telocratic phase of that Interglacial.

    Opis:
    In this paper there are presented results of high resolution transmission electron microscope investigation concerning the structure of the Zn-Al-Si cast zinc alloy with Sr addition for crystal structure refinement after thermo-derivative analysis performed using the universal metallurgical simulator and analyzer platform. The thermo-derivative analysis allows to determine the specific points of the solidifying alloy, which is helpful for phase determination and proper heat treatment condition determination, allowing to reduce the energy costs and obtaining higher mechanical and functional properties. Using transmission electron microscopy, especially selected area diffraction method appliance it was possible to determine the phases occurring in the alloy in the state after chemical composition modification as well as after appliance of very precisely controlled cooling rate. The morphology and size of the microstructure of micro-sized eutectic was possible to determine as well the lattice parameters of the Zn α -phase. Particularly the overview will be also directed on the high resolution transmission electron microscope to achieve good insight into the structural changes on the atomic scale.

    Opis:
    Korekcja niejednorodności kamer detektorów matryc mikrobolometrycznych to problem z którym borykają się konstruktorzy współczesnych kamer termowizyjnych. Stanowisko pomiarowe oparte na zintegrowanym dwupowierzchniowym ciele doskonale czarnym pozwala na wyznaczanie współczynników korekcji niejednorodności. Przedstawiona konstrukcja oraz wyniki badań ciała doskonale czarnego pozwoliły na uzyskanie wyników jednorodności rozkładu temperatury na jego powierzchni na poziomie ±0.0110.015ºC. Przeprowadzone pomiary współczynników niejednorodności detektorów matrycy mikrobolometrycznej potwierdzają poprawność koncepcji działania stanowiska pomiarowego.
    Modern microbolometer array detectors commonly used to sense infrared radiation in 8 - 12 µm range exhibit a non-uniform response of particular array pixels for the same incident power. As a result of this non-uniformity an image degradation called the fixed pattern noise (FPN) occurs. It introduces an additional error component in the thermal representation of the observed scene, thus worsening the performance of an IR camera. In order to compensate this non-uniformity, several correction methods can be employed. Those methods usually base on laboratory measurements on specialized test stands, in which precise blackbody radiation sources are key metrological elements. The presented dual emitter blackbody set meets the high requirements of a standard blackbody for metrological applications. The design of emitters and the applied method of temperature stabilization ensure high uniformity and stability of the temperature distribution over the entire blackbody surface, which was positively verified during laboratory measurements. As a result, the presented blackbody can be used to perform non-uniformity correction of microbolometer focal plane arrays.

    Opis:
    Cast zinc alloys have similar properties to aluminium alloys. The differences are due to the lower melting point and higher density. Zinc has a density of 7.14 g/cm3, a melting point of 419.5°C and the boiling temperature of 906º C. In the temperature range from 150 to 200°C, zinc has good susceptibility to plastic deformation. It is also resistant to atmospheric factor influence, but is not resistant to acids. The main use of zinc alloy, is the production of thin-walled casts that require high precision. Zinc alloys are also used for die casting moulds, housings and covers as well as a variety of devices that are used in the precision industry, electrical engineering, automotive and construction industry. Properly performed chemical modification leads to improve of properties of the produced castings. Therefore it is very important to know how the cast structure with the change of the chemical composition by adding metallic modifiers to the liquid metal. In this work there was studied the effect of chemical modification of cast zinc alloy on the properties and microstructure of the alloys before and after modification. Modified alloys were prepared by adding modifiers in the range of 0.1% to 1% in form of Ti- Sr and B as aluminium master alloy and then cast into the metal moulds. Next the thermo-derivative analysis was performed of the modified Zn-Al-Cu alloy, the microstructure investigation was carried out using light microscopy and scanning electron microscopy with EDS X-ray microanalysis usage as well as hardness was measured of the modified Zn-Al-C alloys.

    Opis:
    The investigations presented in this paper describe surface treatment performed on samples of heat-treated cast magnesium and aluminium alloy. The structure and chemical composition as well as the functional and mechanical properties of the obtained gradient/monolithic films were analysed by high resolution transmission electron microscopy and scanning electron microscopy, Raman spectroscopy, die ball-on-disk tribotester and scratch testing. Moreover, investigation of the electrochemical corrosion behaviour of the samples was carried out by means of potentiodynamic polarisation curves in 1-M NaCl solution. The coatings produced by chemical vapour deposition did not reveal any delamination or defects and they adhere closely to the substrate. The coating thickness was in a range of up to 2.5 microns. Investigations using Raman spectra of the DLC films confirmed a multiphase character of the diamond-like carbon layer, revealing the sp and sp3 electron hybridisation responsible for both the hardness and the friction coefficient. The best wear resistance test results were obtained for the magnesium alloy substrate - AZ61, for which the measured value of the friction path length was equal to 630 m.

    Direct laser interference lithography is a new and low cost technique which can generate the line- or dot-like periodic patterns over large areas. In the present work, we report on direct fabrication of micrometer structures on Si surface. In the experiments the pulsed high power Nd:YAG laser operating at 1064 nm wavelength was used. Two-beam configuration with an angle of incidence of 40° was employed and different laser fluences up to 2.11 J/$cm^2$ were tested. Areas about 1 cm in diameter have been processed with a single pulse of 10 ns. The laser treated samples were analyzed by atomic force microscopy to investigate the surface topography and to measure the size and depth of the achieved structures. We observed periodic line-like arrays with grating period of the order of 1 μm.

    Opis:
    This paper presents results of output signal analysis of uncooled microbolometric focal plane array FPA. The analysis focuses on detectors manufactured by ULIS. The signal has been tested against varying control voltages, it is blind microbolometer biasing VSK and active microbolometer biasing VFID. The working point temperature of the environment was also altered in range from 5°C to 60°C. Such analysis can be used to check the results against current mathematical model of FPA’s behavior and verify validity of the measurement method in varying working conditions. Later it could allow explore possibility to design corrective algorithms.
