Thermal radiation measuring system with a radiation measuring device and a shielded reference device

A radiation measuring system having a radiation measuring device ior measuring incident radiation and a reference measuring device,

• wherein each of said radiation measuring and reference measuring devices comprises:
• at least one electrically insulative carrier foil having a first surface and an opposite surface;
• at least one absorber layer operative to be heated by said incident radiation disposed on said first of said carrier foil, said at least one absorber layer having a preselected size and shape;
• at least one high-value resistor layer operative to be heated by said at least one absorber layer disposed on said opposite surface of said at least one carrier foil proximate said at least one absorber layer;
• at least one thermally conductive layer disposed on said first surface between said at least one absorber layer and said at least one carrier foil, said at least one thermally conductive layer having portions laterally protruding from said at least one absorber layer along said first surface of said carrier foil;
• and
• means for dissipating heat in thermally conductive contact with said laterally protruding portions of said at least one thermally conductive layer such that the heat to be dissipated from said at least one absorber layer is conducted by said at least one thermally conductive layer to said means for dissipating heat, said means for dissiapting heat further comprising means for shielding said at least one thermally conductive layer from said radiation to be measured;
• wherein said radiation measuring system further comprises:
• a housing providing a common support for said radiation measuring and reference measuring devices;
• and
• means disposed in said housing for shielding said at least one absorber layer of said reference measuring device from said incident radiation.

A radiation measuring device comprising:

• an electrically insulative carrier foil having a first surface and an opposite surface;
• a plurality of absorber elements having preselected sizes and shapes disposed on said first surface of said carrier foil, said absorber elements, being heated by the abosorption of incident radiation to be measured;
• a plurality of high-value resistor elements operative to be heated by said absorber elements disposed on said opposite surface of said carrier foil, each of said high-value resistor elements being disposed proximate a respective one of said plurality of absorber elements;
• a plurality of thermally conductive elements, each of said thermally conductive elements being disposed on said first surface between a respective one of said plurality of absorber elements and said carrier foil, each of said plurality of thermally conductive elements having a predetermined portion laterally protruding from each respective one of said plurality of absorber elements;
• and
• means for dissipating heat in thermally conductive contact with said laterally protruding predetermined portion of each of said plurality of thermally conductive elements such that the heat to be dissipated from each of said plurality of absorber elements is conducted by said respective one of each of said plurality of thermally conductive elements.
