Calibration of a Vertical-Scan Long Trace Profiler at MSFCThe long trace profiler (LTP) is the instrument of a choice for the surface figure measurement of grazing incidence mirrors. The modification of conventional LTP, the vertical-scan LTP, capable of measuring the surface figure of replicated shell mirrors is now in operation at Marshall Space Flight Center. Sources of systematic error for vertical-scan LTP are discussed. Calibration method using a test flat mirror and results of measurements are presented.
