Abstract: Devices for detecting electromagnetic radiation, and method of configuring the devices, are disclosed. In one aspect, a pixel array detector includes a plurality of dual-mode pixels arranged in an array. Each dual-mode pixel includes a mixed-mode sensor configured to detect accumulated charge created by electromagnetic radiation incident on the pixel. Each dual-mode pixel further includes a digital-mode sensor configured to count individual photons incident on the pixel. Each dual-mode pixel includes a switch configured to selectively couple the mixed-mode sensor and the digital sensor with a diode associated with the pixel. The pixel array detector further includes a controller configured to configure each pixel of the plurality of dual-mode pixels into either mixed-mode or the digital-mode.
