  • Solar radiation sensor and system including same for measuring solar radiation distribution
    Patent number: 4491727
    Abstract: A solar radiation sensor comprises a semispherical or spherical body member formed with a plurality of radially-extending passageways leading to individual solar-radiation sensors individually oriented and shielded so as to intercept only solar radiation progressing along the radial lines towards the detectors. In one described embodiment, the detectors are recessed within the body member at the bottom of their respective bores, and in a second described embodiment the detectors are all formed in a flat face of the body member and receive the solar radiations by means of fiber optical elements disposed within the bores.
