| 摘要 |
A sensor for the measurement of UV radiation is disclosed which comprises a first layer of phosphor particles directly exposed to incident radiation, which absorb incident radiation and emit visible radiation, a filter for absorbing UV disposed after the phosphor layer and chosen to permit the visible light emitted by the phosphor to pass through, and a photosensor sensitive to the visible light emitted by the phosphors. By disposing the filter after the phosphors, solarization of the filter is substantially eliminated and the sensor remains accurate over long periods of time.
