A surgical imaging system includes a camera, a first imager, and a processing unit. The camera is configured to capture optical images of a surgical site along a first optical path. The first imager is configured to capture first functional images of the surgical site along a second path that is separate from the first optical path. The processing unit is configured to generate a combined view of the surgical site from the captured first functional images and the captured optical images and to transmit the combined view to a display.
