The Johns Hopkins University is developing an adaptive optics coronagraph for the study of circumstellar material at high resolution. The first generation instrument corrects for image motion, i.e., wavefront tilt, using an image motion sensor coupled to a high speed tip/tilt mirror. The image motion sensor is built around a quadrant CCD which detects offsets from the null position. The performance of this device and present results demonstrating its operation in the laboratory are discussed.
