  1. 1. Elastic hyperspectral lidar for detecting coherent backscatter from insects

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Lauro Müller; [2022]
    Nyckelord :Nanosopy; Thin film physics; Hyperspectral; Lidar; Super continuum; Insects; Coherent scattering; Infrared Spectroscopy; Hyperspectral Imaging; Biophotonics; Technology and Engineering;

    Sammanfattning : Insects play a major role in the ecosystem and are an important factor for biodiversity. Using laser remote sensing to distinguish and monitor the millions of insects in-situ, holds large potential to speed up and improve the otherwise time consuming process of trapping and subsequent analysis.

  3. 2. Implementation of Scheimpflug Lidar for Entomological Monitoring of Bark Beetles

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Jonathan Peterson; [2020]
    Nyckelord :Scheimpflug Lidar; Lidar; Bark beetles; Forestry; Entomological monitoring; Physics and Astronomy;

    Sammanfattning : Bark beetles are responsible for great damages to Swedish forestry every year. This project focuses on a method of entomological lidar called Scheimpflug lidar to detect and monitor bark beetles. Scheimpflug lidar uses old techniques from photography to achieve a deep field of focus to resolve objects over long distances. LÄS MER

  4. 3. Unbiased pitch detection and phase estimation in entomological lidar

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Johan Fogelmark; [2019]
    Nyckelord :Entomological lidar; wing beat frequency estimation; phas; Mathematics and Statistics;

    Sammanfattning : Good insect monitoring is important for both disease vector control and e?cient usage of pesticides in farming. Entomological lidar has been proven useful for detecting and monitoring insects. For every insect that transit the laser beam a backscatter signal containing species-specific information is obtained.

  5. 4. Unbiasing entomological kHz Scheimpflug LIDAR data

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Alexandra Andersson; [2018]
    Nyckelord :Entomological LIDAR; Insect detection; Wing-beat frequency; Unbiasing of analysis model; Physics and Astronomy;

    Sammanfattning : Insects can be mapped using a method called Scheimpflug Lidar (LIght Detection And Ranging). Sending out light in the near infrared range and detecting the backscattered echo, it is possible to resolve flying organisms in range and time. Insect observations can be distinguished from the background signal through adaptive thresholding. LÄS MER

  7. 5. Short-Wave Infrared Lidar on Atmospheric Aerosols and Insects

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Mariam Andersson; [2017]
    Nyckelord :Lidar; Scheimpflug; Time-of-Flight; Remote sensing; Atmospheric sensing; Physics and Astronomy;

    Sammanfattning : This thesis focusses on the implementation of two elastic lidar (light detection and ranging) techniques for the monitoring of atmospheric aerosols and insects at short-wave infrared wavelengths. Data acquisition software was developed for a time-of-flight system, housed in the Lund University Mobile Biosphere Observatory (LUMBO), with consideration to the intended entomological application.
