Abstract:
1. A method of 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 reflective 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 second beam of light at said reflecting point upon said reflective material, said second beam of light being of sufficient energy so as to change the amount of light in said reflecting beam by electromagnetic interaction with said first beam of light at said reflecting point, said reflective material being supplied with an electrical contact placed on said reflective material so as to be capable of placing a voltage through said reflective material at said reflecting point; and (d) detecting the change in the amount of light in said reflecting beam as a result of said electromagnetic interaction.
