A pixel array may include first pixels having photodiodes in the first image sensor die and second pixels having photodiodes in the second image sensor die. The first pixels may be optimized to detect a first type of electromagnetic radiation (e.g., visible light), whereas the second pixels may be optimized to detect a second type of electromagnetic radiation (e.g., infrared light). Light guide channels may be formed in the first image sensor die to help guide incident light to the photodiodes in the second image sensor substrate. The first and second image sensor dies may be bonded at a wafer level. A first image sensor wafer may be a backside illumination image sensor wafer and a second image sensor wafer may be a front or backside illumination image sensor wafer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging systems with stacked image sensors","description":"An imaging system may include a first image sensor die stacked on top of a second image sensor die.
