Radiation Reflection Device

Abstract

A radiation reflection device used to focus radiation from a moving source onto a stationary receiver is disclosed. The primary application of such an invention relates to reflecting the radiation from the sun onto a stationary target. The device orients a reflective surface to a position necessary for imaging using a parallelogram type half-angle system. The device may be used singly or in a ganged array.

 said mirror frame is fixed to said reflective surface; 
   mirror frame guides wherein;
 said mirror frame guides are fixed to said mirror frame; 
 said mirror frame guides comprise one or more parallel slots; 
   one or more incidence linkages and one or more reflection linkages wherein;
 said incidence linkages are aligned perpendicular to the incidence vector; 
 said reflection linkages are aligned perpendicular to the reflection vector; 
 said incidence linkages and said reflection linkages are interconnected in a parallelogram pattern; 
 vertices of said parallelogram pattern define a parallelogram bisecting line that bisects the angle between said incidence linkages and said reflection linkages; 
   one or more traversing bolts wherein;
 each of said traversing bolts intersects one of said vertices of said parallelogram bisecting line; 
 each of said traversing bolts passes through one or more incidence linkages, one or more reflection linkages and one or more of said slots of said mirror frame guides; 
   a main shaft wherein;
 said mirror, said mirror frame, said incidence linkages, and said reflection linkages, are rotatable about said main shaft; 
 said mirror, said mirror frame, said incidence linkages, and said reflection linkages are mounted, either directly or indirectly, on said main shaft. 
   
     
     
         2 . A device of  claim 1  wherein said radiation reflection device is implemented in a heliostat wherein said radiation reflection device comprises:
 a tilt motor wherein;
 one of said incidence linkages is rotated, directly or indirectly, by said tilt motor; 
 one or more of said reflection linkages is mounted, directly or indirectly, to said main shaft wherein said main shaft is aligned along the reflection vector; 
   a pan motor wherein;
 said pan motor is connected to said main shaft; 
 said pan motor can cause said mirror, said mirror frame, said incidence linkages, and said reflection linkages to rotate about said main shaft. 
   
     
     
         3 . A device of  claim 2  wherein said radiation reflection device further comprises a sensor plate fixed to one or more of said incidence linkages wherein;
 said sensor plate includes a pair of pan sensors;   said sensor plate includes a pair of tilt sensors;   said pan sensors produce a control signal which can be used to control said pan motor;   said tilt sensors produce a control signal which can be used to control said tilt motor.   
     
     
         4 . A device of  claim 1  wherein said radiation reflection device is implemented in a ganged array wherein;
 said radiation reflection device comprises a cable wherein:
