Paper Abstract

X-Ray telescopes with optics and detectors at opposite ends of semi-rigid, extendable booms can improve their imaging performance if the flexing of the boom is measured and removed in image reconstruction. This has been accomplished on previous missions with analog position detectors and highly stable laser pointing indicators. This report shows that a flight-proven digital imaging system observing LED sources, can achieve as high or higher precision measurements without extensive calibration at modest cost.
