Real Time FPGA-Based Crosstalk Elimination for Multichannel Interferometry Systems in Fusion Diagnostics

Infrared (IR) interferometry is a well-known method for measuring the Line-Integrated electron Density (LID) of fusion plasmas. In the TJ-II stellarator, an FPGA-based IR-interferometer has recently been installed to accurately measure the LID of the plasma in real time. To guarantee the correct functionality of the interferometer and achieve high precision rates, it is essential to maximize the S...
