WebMar 31, 2024 · In addition, tunable FMCW laser sources enable lidars with configurable operating wavelength thus further enhancing the immunity of coherent lidars to external light interference. Coherent lidar, also called FMCW lidar, uses coherent technology to greatly increase range and sensitivity by measuring the phase of the reflected light instead of ... WebFMCW LIDAR works much in the same way, but instead of measuring the time and power of a reflected laser, it measures the frequency of the reflection against a constant waveform, and uses some spicy math to figure out the distance of the object based on the Doppler shift produced by interfering the constant waveform against the return waveform.
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 …
