- Abstract
Light Detection and Ranging (LiDAR) commonly uses fiber optic as the transmission medium because it can monitor over long distances, has strong resistance from extreme environments, and has anti-electromagnetic interference. According to previous research, LiDAR characteristics related to the effect of fiber optic length on FMCS-based LiDAR applications have not been analyzed. The novelty of this research is that it uses a distance sensor designed using the FMCW-based LiDAR method. Therefore, this study in FMCW-based LiDAR was carried out to determine the characteristics of optical fiber in length variations. Analysis was obtained by comparing the effect of optical fiber length on attenuation through power loss and time delay during the transmission process. When the time delay occurred, the photodetector transmitted and reflected the beam. Fiber optic length is exponentially related to attenuation with y = 0.2064e0.0073x. Meanwhile, the time delay is linearly proportional with y = 69.849x + 9.149. Besides, the study also gets the effect of optical fiber absorption, connection, bending, lens attenuation, free space, and refractive index homogeneity that can be used as the basis for the following LiDAR technology development.
