Scan frequency vs. Cross Track and Down Track Resolution
The system PRF is the number of laser shots/unit of time. If the system PRF is constant but the scan frequency increases, the Cross Track spacing decreases but the Down Track spacing increases (Figure 42).
The total area coverage remains the same, but there are fewer laser spots across the swath because the xxx scans the full width more quickly, effectively spreading the same amount of spots across more than one swath:
