Scene adaptive endoscopic illuminator with fluorescence illumination

Abstract

Endoscopic illuminator devices and methods are provided with an adaptive illumination profile. An endoscopic illuminator includes a first and a third illumination element adapted for coupling first illumination light into a light input of an endoscope for illuminating a central area of a field of view of the endoscope. A second and a fourth illumination element are adapted for coupling second illumination light to the light input for illuminating a peripheral area of the field of view, arranged relative to the first illumination element such that the first illumination light enters the light input at a substantially different angle from the first illumination light, and having an illumination level adjustable separately from that of the first and third illumination element. The second and fourth illumination elements provide imaging light in a different spectral band than the first and third illumination elements.
