Patent number: 10598769Abstract: The invention relates to a coaxial direct-detection LIDAR system for measuring velocity, temperature and/or particulate density. The system comprises a laser source for emitting a laser light beam having a lasing center frequency along an emission path. The system further comprises an optical delivery system arranged in the emission path of the laser source, the optical delivery system being arranged for delivering the laser light beam in a measuring direction, the optical delivery system further being configured for collecting a return signal backscattered along the measuring direction. Finally, the system comprises a detector system arranged to receive the return signal from the optical delivery system, the detector system comprising a narrowband optical filter and a detector, the narrowband optical filter having a filter center frequency of a pass-band, wherein the center lasing frequency and/or the center filter frequency may be scanned.Type: GrantFiled: May 6, 2014Date of Patent: March 24, 2020Assignee: Danmarks Tekniske UniversitetInventors: Peter John Rodrigo, Christian Pedersen

Patent number: 9285385Abstract: A vector velocimeter includes a laser emitting a measurement beam with a wavelength ?, for illumination of an object in a measurement volume to create a signal beam, a reference beam generator generating a reference beam, and a first detector arranged such that the signal beam and the reference beam, propagating at a first angle ? relative to the signal beam, are incident thereon. The first detector includes an array of first detector elements to convert the intensity of the interfering signal beam and reference beam incident thereon into an oscillating electronic detector element signal when the fringe pattern formed thereby moves across the first detector array. A signal processor generates a velocity signal corresponding to a first velocity component of movement of the object in the measurement volume in the longitudinal direction thereof based on the electronic detector element signals from each of the first detector elements.Type: GrantFiled: July 18, 2011Date of Patent: March 15, 2016Assignee: TECHNICAL UNIVERSITY OF DENMARKInventors: Steen Hanson, Michael Linde Jakobsen, Theis Iversen, Peter John Rodrigo, Christian Pedersen
