Abstract: Exemplary apparatus and optical systems for forward and side view apparatus are described. These apparatus include a light focusing element, a grating element inclined with respect to the optical axis of the apparatus, and a transparent element. The transparent element has a proximal surface in contact with the grating element and an inclined distal surface. Such apparatus can be sued as spectrally encoded endoscopy (SEE) probes.

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.
