Abstract:
1. A solid-state transmission-mode optical system for tracking a light source, comprising: a. a first member of a transparent rotor having a first refractive index, b. a second member of said transparent rotor having a second refractive index, c. a first member of a transparent stator also having said first refractive index, d. a second member of said transparent stator also having said second refractive index, e. a flat optical boundary, positioned between said first and said second members of said transparent stator, and formed by the physically contiguous joining of said first and said second members of said transparent rotor, wherein said first refractive index is different from said second refractive index, and said first and second refractive indices are selected to enable refractive transmission of light across the optical boundary of said first and second members of said transparent rotor in a predetermined output direction for receiving refracted light from the light source, and f. a means to induce a torque in a desired direction on the entirety of said first and said second members of said transparent rotor relative to said first and said second members of said transparent stator, whereby the induced torque on said transparent rotor, relative to said transparent stator, causes said transparent rotor to track said light source so that light passing through the said transparent rotor is refracted at said optical boundary and causing said light to be redirected to a desired output direction for concentration, distribution, or energy conversion.
