1. A LIght Detection And Ranging (LIDAR) system, comprising:
a first laser subsystem configured to transmit a first laser beam at a first location on an object at a time;
a second laser subsystem configured to transmit a second laser beam at a second location on the object at the time; and
an analyzer configured to analyze data based on laser beams produced by the LIDAR system, the analyzer configured to calculate a first range based on a first reflected laser beam reflected from the object in response to the first laser beam, the analyzer configured to calculate a second range based on a second reflected laser beam reflected from the object in response to the second laser beam, the analyzer configured to detect a vibration velocity field over the object;
the first location being targeted by the first laser subsystem and the second location being targeted by the second laser subsystem such that a first displacement due to the vibration velocity field at the first location is substantially the same as a second displacement due to the vibration velocity field at the second location while the vibration velocity field is being detected.
