For future burning plasma experiments, all diagnostics must be re-evaluated in terms of their measurement capabilities and robustness in the harsh, high-temperature environment. This is certainly true for interferometry measurements where conventional approaches may not be ideal and interpretation may require modification due to high plasma temperatures. Optimizing these systems to provide maximum information is crucial to understanding burning plasma dynamics. This paper explores a variety of phase measurement techniques for the main body and divertor regions that can be utilized on fusion plasma experiments like ITER and beyond.
