  2. 2. Combined speckle interferometry and speckle correlation for non-destructive testing

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Angelica Andersson; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimentell mekanik; Experimental Mechanics;

    Abstract : When a sample is studied during loading in a tensile test machine, the sample is often exposed to rigid body motions during loading at the same time as it deforms due to tension. Therefore, the small deformation field is hard, or impossible, to measure when it is overlaid by a large motion. READ MORE

  3. 3. Partially Coherent Laser Radiation - Modeling and Application to Optical Microlithography

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Christer Rydberg; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microlithography; coherence; temporal speckle; partial coherence; optical propagation; number of degrees of freedom; dynamic speckle;

    Abstract : This work deals with a type of light that has properties somewhere between blackbody radiation and conventional laser light; such light is referred to as partially coherent. One example is the radiation from the pulsed excimer laser, which is used in the manufacturing of most of the worlds integrated circuits. READ MORE

  5. 5. On perfusion estimation using ultrasound

    University dissertation from Department of Electrical Measurements, Lund University

    Author : Tomas Jansson; Lunds universitet.; Lund University.; [1999]

    Abstract : Popular Abstract in Swedish Denna avhandling behandlar analys och förbättringar av en metod att mäta blödgenomströmning i vävnad med kontinuerlig ultraljudsdoppler. Tidigare har stora variationer i detekterat perfusionsvärde observerats som en effekt av speckle, eller våginterferens. READ MORE
