In order to test the long distance detection capability of LiDAR in laboratory
a method of time delay generated by laser propagating in fiber is proposed for equivalent time delay in air.First
the theoretic analysis of this method is completed according to propagation equation of LiDAR system
and the impact of fiber attenuation on the feasibility of this method is gained quantitatively.Then
two ways of forthright transmission and circulating loop transmission are designed with 1.55 μm wavelength laser.The distance simulation with fiber is introduced to the LiDAR system.The time delay of 69.1 m fiber is equivalent to that of 101.4 m in air.Laser transmits through the 69.1 m fiber
and then enters in the LiDAR transmitter model to detect a simulacrum object which is 3.5 m in the free space and the 3D image of the surface of the object is obtained.
