Abstract
An image sensor for a Time-of-Flight imaging system is disclosed that includes at least one primary sensor having a photodetector that includes a photovoltaic junction formed at least partially in a germanium-containing material that includes germanium at an atomic percentage greater than 50%, and at least one secondary sensor having a photodetector that includes a photovoltaic junction formed in a second material, such as a silicon-containing material, that includes germanium at an atomic percentage between 0% and 50%. The primary sensor may detect Time-of-Flight measurement signals and the secondary sensor may detect background light, such as sunlight, to correct for background light interference.
