Abstract
An apparatus for warning a user that a radiation source is likely to fail in the near future comprises a radiation source, having a radiance; a detector, responsive to the radiance; a memory, having a radiance measurement unit for collecting radiance data and a failure prediction unit for determining that the radiation source end of life is near; and a processing unit, coupled to the detector and the memory. A method for warning a user that a radiation source is likely to fail in the near future comprises the steps of collecting radiance data from the radiation source; determining if the radiation source's end of life is near; and warning a user if the radiation source's end of life is near.
