Abstract: The present disclosure provides apparatuses and methods for color imaging and an increased field of view using spectrally encoded endoscopy techniques. At least one of the apparatuses includes an illumination unit having two or more spectrally dispersive gratings positioned, for example, on different planes or on the same plane but having grating vectors at an angle to each other such that bands of spectrally dispersed light propagating from the gratings propagate on different planes.

Abstract: The present invention relates generally to apparatus and methods for endoscopy which includes a probe, a first and a second optical fiber to guide light, a third optical fiber to capture light; and a switch configured to operate the first optical fiber and second optical fiber. Light dispersed by the first optical fiber at least partially overlaps light dispersed by the second optical.
