Abstract
A camera captures visual and infrared images through a single lens assembly by inserting a beam splitter along the path of light proceeding through the lens assembly to pass a first light spectrum to a first image sensor along the lens axis and reflect a second light spectrum to a second image sensor along a reflection axis. For example, a hot mirror reflects infrared light along the reflection axis and passes through visible light along the lens axis, and a cold mirror reflects visible light along the reflection axis and passes infrared light through along the lens axis. Processing of an infrared image to define boundaries of a visible image provides a high quality composite image.
