Abstract
An imaging system includes an image sensor and an optical filter. The image sensor captures image data in response to incident light. The optical filter filters the light and includes a dual window transmission spectrum. The dual window transmission spectrum includes a first transmission window having a first pass band aligned to pass visible light and a second transmission window having a second pass band overlapping with an absorption band of infrared light in Earth's atmosphere.
