Design of a digital holography system for PFC erosion measurements on Proto-MPEX

A project has been started at ORNL to develop a dual-wavelengthdigital holography system for plasma facing componenterosionmeasurements on prototype material plasma exposure experiment. Such a system will allowin situ real-timemeasurements of componenterosion. Initially the system will be developed with one laser, and first experimental laboratorymeasurements will be made with the single laser system. In the second year of development, a second CO2 laser will be added andmeasurements with the dual wavelength system will begin. Adding the second wavelength allowsmeasurements at a much longer synthetic wavelength.
