The advancement in optical technology based metrology has been significant over recent years. Many applications utilize the Frequency Scanning Interferometry (FSI) technique for short and long-range precision measurements. This paper discusses the design and development of a cost-effective FPGA based data acquisition solution for FSI system for long-range measurement. The proposed hardware uses the 160MS/s ADC interfaced with an FPGA via an LVDS interface. The acquisition hardware utilizes the external clock signal generated from the reference interferometer which reduces the non-linear effect of the tunable laser for improved precision. The design and development of a low noise comparator design for an external sampling clock is also presented.
