Abstract:

A line imager comprising a semiconductor body a planar, transparent piezoelectric body having a main surface overlying and in proximity to the semiconductor body wave propagation means for propagating acoustic waves on the main surface of the piezoelectric body to create traveling potential wells in the underlying semiconductor body a traveling potential well path located in the semiconductor, the traveling potential well path beginning at the wave propogation means and extending straight away therefrom semiconductor depletion means for depleting the semiconductor of majority charge carriers along the traveling potential well path, the depletion, means located atop the piezoelectric body a gate located on the semiconductor body and alongside and parallel to the traveling potential well path and adjoining the semiconductor depletion means.
