Abstract

Passive detector structures for imaging systems are provided, which are based on a coefficient of thermal expansion (CTE) framework. With such framework, a CTE-based passive detector structure includes a detector member that is configured to expand or contract in response to thermal heating resulting from photon exposure. The expanding/contracting CTE detector structure is configured to exert mechanical forces on resistor and/or capacitor circuit elements, which are part of an oscillator circuit, to vary the resistance and capacitance of such circuit elements and change a frequency or period of oscillation of an output signal of the oscillator circuit. The change in the frequency or period of oscillation of the output signal of the oscillator circuit is utilized to determine an amount of photon exposure of the CTE-based detector.
