An artificial cornea for sensing and integrating UV radiation in real time. The cornea includes an EPROM array adapted to be exposed to UV radiation. Individual bits of the EPROM array are set prior to being exposed to the UV radiation. In response to being exposed to the UV radiation predetermined ones of the individual bits are erased. Means for monitoring, in real time, the locations of the predetermined erased bits are provided and, in response, a record is formed of the energy distribution of the UV radiation across the EPROM array.
