  • Velocity measurement device and laser range finder using a coherent detection
    Patent number: 6100516
    Abstract: The invention relates to a velocity measurement device of the coherent detection type comprising:an active laser medium (10),an input mirror (M.sub.1) and a first output mirror (M.sub.3) defining, with the laser medium, a first resonant cavity of quality factor Q.sub.max making it possible to emit a laser beam (4),a second output mirror (M.sub.2) defining, with the active laser medium (10) and the input mirror (M.sub.1), a second resonant cavity of quality factor Q.sub.min (<Q.sub.max), making it possible to amplify a measuring signal from a target which has intercepted the laser beam (4) emitted with the aid of the first resonant cavity.
