Interconnected array of photosensors for simultaneously sensing light intensities at each of a number of locations

A monolithic array for sensing the intensity of electro-magnetic radiation at each of a plurality of locations comprising:

• an electrically insulating substrate;
• a plurality of lengths of an electrically conductive material disposed on said substrate;
• at least one photoresponsive diode disposed on each of said lengths of conductive material, each of said photoresponsive diodes having a first terminal of a first polarity and a second terminal of a second polarity opposite said first polarity, each of said photoresponsive diodes having its second terminal in electrical contact with the length of conductive material on which it is disposed;
• at least one non-photoresponsive diode disposed on each of said lengths of conductive material, each of said non-photoresponsive diodes having a third terminal of said first polarity and fourth terminal of said second polarity, each of said non-photoresponsive diodes having its fourth terminal in electrical contact with the length of conductive material on which it is disposed;
• a first electrically conductive interconnection disposed on each of said first terminals of said photoresponsive diodes and electrically connecting together all of said first terminals to form one terminal of said array;
• and
• a plurality of second electrically conductive interconnections each disposed on one of said non-photoresponsive diodes on one of said lengths and on a different one of said lengths, said second interconnections electrically connecting said non-photoresponsive diodes in like-polarity series, one of said second interconnections forming a second terminal of said array.
