Abstract :
Novel semi-transparent optical position sensors (‘ALMY sensors’) have been developed for the alignment monitoring systems of modern large-area tracking detectors. More than 10 sensors can be aligned along one laser beam. The thin-film amorphous silicon strip sensors provide up to 90% transmittance for red laser light combined with minimum beam distortion and a typical position resolution of 1 μm over a sensitive area of several square centimeters.
