Abstract: A radiation detector includes a plurality of detector elements arranged on a detector substrate in an interdigitated linear array. A thermoelectric or other cooler is attached to the lower surface of the detector substrate. A pair of interconnect boards is positioned on opposite sides of the detector substrate. The detector elements, substrate, cooler and pair of boards are received in a sealed housing and a radiation transmitting window in the housing permits radiation to pass into the housing and strike the detector elements. A plurality of conductive pins extends through the housing and terminates at electrical traces on the interconnect boards. A thermistor or other temperature sensor is attached to the detector substrate and, through control of the thermoelectric cooler, maintains the detector substrate at a desired operating temperature.

Abstract: A detector includes a plurality of detector elements in a linear array. A bias source is connected to the input terminal of each detector element. The bias source includes a first bias connected to the input terminals of a first set of detector elements including alternating detector elements and is also connected through an associated measurement device to the output terminals of a second set of detector elements including the remaining detector elements. The bias source also includes a second bias, different from the first bias, and connected through an associated measurement device to the output terminals of the first set of detector elements. The second bias is also connected to the input terminals of the second set of detector elements.
