← ScienceWhich consequence results when coherence is lost inside a pulsed lidar system utilizing stimulated Brillouin scattering?
A)Range resolution reduces significantly✓
B)Frequency chirping compensates errors
C)Pulse duration maintains the same
D)Peak power increases quadratically
💡 Explanation
A loss of coherence in the Brillouin amplification process introduces phase variations into the transmitted pulse, thus reducing achievable range resolution because constructive interference is diminished. Therefore, range resolution suffers severely rather than benefits, differing from ideal coherent pulsed systems.
