Apparatus and Method for Closed Loop Control of Heliostat Motion

This invention is an apparatus and method for controlling the motion of heliostats, which are mirrors that reflect sunlight towards a common target. For heliostats to be maximally efficient, they must be able to shift in orientation precisely as the Sun’s relative position to the Earth changes. This technology utilizes a beamsplitter perpendicular...
