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

    Author : Christer Rydberg; Chalmers tekniska högskola; []
    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

  4. 2. Improved inspection and micrometrology of embedded structures in multi-layered ceramics : Development of optical coherence tomographic methods and tools

    Author : Rong Su; Lars Mattsson; Peter Ekberg; Jerzy Pluciński; KTH; []
    Keywords : Metrology; Optical Coherence Tomography; Ceramics; Embedded Structure; Multilayer; Nondestructive Testing; Optical Inspection; Critical Dimension Measurement; Infrared Imaging; Scattering; Mie Calculation; Image Processing; Monte Carlo Simulation; 测量学， 光学相干断层扫描术，陶瓷，嵌入式结构，多层，无损检测，光学检测，关键尺寸测量，红外成像，散射，Mie计算，图像处理，Monte Carlo模拟; SRA - Production; SRA - Produktion;

    Abstract : Roll-to-roll manufacturing of micro components based on advanced printing, structuring and lamination of ceramic tapes is rapidly progressing. This large-scale and cost-effective manufacturing process of ceramic micro devices is however prone to hide defects within the visually opaque tape stacks. READ MORE

  5. 3. Optical Coherence Tomography for Dermatological Applications

    Author : Jakob Borup Thomsen; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; medical imaging; skin cancer diagnostics; optical imaging; blood flow; treatment monitoring;

    Abstract : Optical coherence tomography (OCT) is a non-invasive optical imaging technique providing approximately 10 micrometer resolution of tissue in vivo. Within ophthalmology, OCT has already proven its value and is routinely used for diagnosing retinal diseases. READ MORE

  6. 4. Ultracold atoms in optical potentials : from noise-induced transport to superfluidity

    Author : Martin Zelan; Claude Dion; Sile Nic Chormaic; Umeå universitet; []
    Keywords : Brownian motors; noise-induced transport; superfluidity; ultracold atoms; optical potentials; optical lattices; laser coooling; fysik; Physics;

    Abstract : In this thesis, both experimental studies and numerical simulations of ultracold atoms in optical potentials are presented in a collection of nine scientific papers. In particular, noise-induced transport in dissipative optical lattices and superfluid properties of Bose-Einstein condensates have been studied. READ MORE

  7. 5. Statistical optics and optical elements for microtechnologies: Partial coherence, lithography and microlenses

    Author : Christer Rydberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse methods; microlenses; optical propagation; partial coherence; dynamic speckle; lithography;

    Abstract : The scientific problems treated in this thesis are expressed within the framework ofstatistical optics and are generated out of the optical lithography industry. Opticallithography uses partially coherent light, i.e. light with a random wavefront, toincrease the performance of the lithographic process. READ MORE
