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.
