摘要： A dynamically controllable polarizer integrated with an imaging detector to provide “on demand” variable polarization measurements. In one example, an imaging system includes a detector array including a plurality of pixels arranged in a two-dimensional array, and a dynamic polarizer coupled to the detector array, the dynamic polarizer including at least one patterned layer of a material disposed on the detector array, the material being operable to alter its conductivity responsive to an applied stimulus to reversibly transition between a polarizing state and a non-polarizing state.

摘要： A method for detecting both gamma-ray events and neutron events with a common detector, where the detector includes a layer of semiconductor material adjacent one side of a glass plate and a Gd layer on an opposite side of the glass plate, between the glass plate and a layer of silicon PIN material to form an assembly that is bounded by electrodes, including a semiconductor anode on one side of the semiconductor layer, a cathode connected to the glass plate, and a Si PIN anode on a side of the Si PIN layer opposite the semiconductor anode. The method includes the steps of: (1) monitoring the electrical signal at each of the semiconductor anode and the Si PIN anode, and (2) comparing signals from the semiconductor anode and the SI PIN anode to differentiate between gamma-ray events and neutron events based on predetermined criteria.
