“…CH4 in the case of the MERLIN frequency reference unit. 2,3 In case of a multi species instrument this approach means that for every gas species, a laser source has to be carried along in order to allow for the calibration of the wavemeter. A frequency comb approach will not work with a wavemeter as due to the FSR ambiguity of the wavemeter single mode laser light of high spectral purity is necessary of the maximum possible accuracy of the wavemeter shall be achieved.…”

This work aims to provide details on the latest technological developments regarding LiDAR (Light Imaging Detection And Ranging) systems, with particular reference to the techniques, architectures, and methodologies partially or entirely implemented by means of the FPGA (Field Programmable Gate Array) environment. Currently, LiDAR technology is considered of great interest as it is widely employed in a variety of application fields, such as automotive, seismology, archaeology, metrology, and military. For this reason, the required performances are gradually increasing, which leads to complex and stringent solutions. The growth in LiDAR systems’ complexity suggests the use of high-end general-purpose computing units such as central processing units to perform very complex tasks and FPGAs to perform multiple tasks in real-time through the implementation of dedicated computational blocks. The latter, in recent architectures, are therefore used for the execution of specific tasks that require high computational speed and system flexibility. This paper reports some case studies recently applied in the LiDAR field, with the aim of illustrating the role of FPGA technology and its benefits.
