Abstract
According to an embodiment, an avalanche pixel sensor includes a substrate having opposite first and second surfaces, first sensor elements operating in breakdown mode situated on the first surface of the substrate for detecting ionizing radiation from a radiation-emission source, second sensor elements operating in breakdown mode situated on the second surface of the substrate, the second sensor elements each paired with a corresponding first sensor element to experience substantially coincident breakdown in response to ionizing radiation. Logic elements are each electrically interconnected to a respective pair of first and second sensor elements for receiving a signal or signal representing the substantially coincident breakdown of the respective pair to be distinguished from a dark signal even in either of the pair of the first and second sensor elements. Additionally, a detector array, a sensing apparatus, and a method of detecting ionization radiation using first and second sensor elements disposed on opposite sides of a substrate are also provided.
