Abstract
Dark current and associated random telegraph signals are studied in short-wave infrared image sensors. The effects of space radiation on these parameters are analyzed and modeled to understand the degradation in this indium–gallium–arsenide (InGaA)-based technology. Multiple proton tests were performed to cover the space mission range of radiation dose. Comparison with existing data and damage factors is provided and highlights the behavior of such technology against radiation doses.
