We propose and demonstrate a new class of LIDAR technique based on optical frequency comb, named frequency-modulated comb LIDAR (FMcombLIDAR), to realize both high resolution and long distance measurement, overcoming the trade-off between the scan range and the coherence length. In FMcomb LIDAR, the multiple carriers from an optical frequency comb are used, enabling the coherent stitching of the multiple carriers. FMcomb LIDAR allows for a resolution equivalent to scanning by many comb modes while scanning only by the comb mode spacing.
