A Measuring Device for Holograms from Large Volume Bubble Chambers
Measuring full-size reconstructed holographic images of bubbles from a large bubble chamber presents problems of size, rapid location of the desired event, and precise measurement of a local region. We present a conceptual design of a practical system using computer-controlled mirrors to align the desired vertex region along the axis of motion of a vidicon whose field of view includes the local region. Precise measurements of short-decay paths are then made by fine adjustments of the vidicon position. This method requires normal stereo photography for scanning and preliminary reconstruction of the event.
