    Författare :Per Synnergren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : The goals of this work were not only to develop new measuring techniques, but also to validate their performance, in terms of accuracy, spatial resolution, etc., by performing carefully chosen experiments. The measuring techniques were also to be applicable to industrial problems in production, control or product development. LÄS MER

  5. 4. Multiplexed Digital Holography incorporating Speckle Correlation

    Författare :Davood Khodadad; Pascal Picart; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik; Technology byts ev till Engineering ;

    Sammanfattning : In manufacturing industry there is a high demand for on line quality control to minimize the risk of incorrectly produced objects. Conventional contact measurement methods are usually slow and invasive, meaning that they cannot be used for soft materials and for complex shapes without influencing the controlled parts. LÄS MER

  7. 5. Digital speckle photography and digital holography for the study of transparent media

    Författare :Eva-Lena Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimentell mekanik; Experimental Mechanics;

    Sammanfattning : In the fields of combustion and fluid mechanics, temperature- and density fields are of interest to measure. Optical measurement methods may be used to study such transparent media. Flames, gases and liquids are examples of transparent media, often called phase objects in an optical context. LÄS MER
