Processor-controlled light-admitting heliostat

A heliostat optimized to be positioned near a skylight or other aperture is disclosed. The heliostat comprises a plurality of reflective elements arranged in a substantially planar array, each element being mounted so as to be rotatable about a longitudinal axis of rotation. A first motor rotates the array about an axis substantially perpendicular to the plane of the array; and a second motor rotates the reflective elements about their respective axes of rotation. A processor provides control signals to operate the first motor as required to orient the array such that the respective axes of rotation of the reflective elements are substantially perpendicular to an azimuth to the sun and to operate the second motor as required to rotate the reflective elements about their respective axes of rotation to position the reflective element to reflect the sun's light to a target area.
