ABSTRACT:
A laser is modulated in accordance with an input signal of time varying value. The modulated beam is intercepted by a Bragg cell acoustically modulated in accordance with one or more preselected control frequencies from a selectable source of such frequencies. The beam is deflected by an amount or amounts dependent on the acoustically modulated frequency or frequencies. A plurality of photodetectors are positioned to intercept the deflected beam at its respective possible deflection angles and to convert optical signals so recieved into electrical output signals. Thus by choice of control frequency, a signal corresponding to the input signal can be caused to appear at the output of one or more photodiodes.
