LiDAR laser applications have grown dramatically in the past few years. Despite being invented in 1960, its acceptability and applications began to grow after 1990. As a result, this technology is now used in almost every industry, including agriculture, forestry, military, mining, transportation, etc. LiDAR is an abbreviation for Light Detection And Ranging. As the name implies, this technique measures the distance between objects by using light waves or a light source. To put it another way, it is used in range-finding applications. The majority of LiDAR works on the Time of Flight principle. According to this principle, the laser in the form of a pulse is directed at the object, and the reflection or scattering from the object is measured by a detector built into the system. The detector determines the difference between the transmitted and received pulses. So this is the fundamental idea underlying all LiDAR systems.
