Abstract:
1. A method of providing a pulsed optical signal by changing the amount of reflected light from a beam of light, said method comprising: (a) providing a substrate bearing a film of a reflective material, said reflecting material is selected from the group consisting of semiconductive materials; (b) directing a first beam of light at a reflecting point upon said reflective material so as to create a reflecting beam therefrom; (c) directing a pulsed second beam of light at said reflecting point upon said reflective material, said reflective material being supplied with an electrical contact placed on said reflective material so as to be capable to placing a voltage through said reflective material at said reflecting point, so as to create pulses in the amount of light in said reflecting beam thereby creating a pulsed reflecting beam; and (d) transmitting said reflecting beam along an optical conduit.
