WebDec 3, 2024 · Coherent detector vs. coaxial sensor design If the light is emitted coherently, as in frequency modulation, it must, of course, also be detected continuously. For this reason, FMCW uses coherent detectors, which are very sensitive since only the specifically emitted coherent light should be filtered and recorded. WebExamples of FMCW laser radar systems and methods described herein may segment the processing of a broader bandwidth frequency chirp into multiple shorter-duration (e.g., lower bandwidth) frequency chirps. This segmentation may have the benefits in some examples of improving the measurement duty cycle and range resolution, and/or allowing for more …
