Projected-Fringe Profilometer Maps Erosion Of Electrode
Abstract
Report describes use of projected-fringe, phase-stepping optical profilometer to measure three-dimensional shape of surface of molybdenum electrode eroded in ion engine. Instrumentation used in these measurements similar to that described in "Projected-Fringe, Phase-Stepping Profilometer" (LEW-14996).
