An apparatus comprising at least: a first waveguide; a second waveguide; and a diffractive element. The first waveguide guides a first band of onto the diffractive element such that the first band is diffracted at an mnon-zero order over a first range of angles. The second waveguide guides a second band onto the diffractive element such that the second band is diffracted at the mnon-zero over the first range of angles. The second waveguide guides a third band onto the diffractive element such that the third band is diffracted at the nnon-zero order over the first range of angles. Wavelengths of the first band, the second band, and the third band do not overlap with each other. The morder and the norder are different from each other.

Multi-bandwidth spectrally encoded endoscope

A spectrally encoded endoscopic probe. The probe has a light guiding component, a light focusing component, and a grating component. The probe is configured such that a set of light beams of multiple wavelengths are diffracted by the grating component in different orders at substantially the same angle. The set of light beams includes at least 3 light beams. Each light beam among the set of light beams is associated with a different wavelength.

Spectrally encoded probe with multiple diffraction orders

Exemplary spectrally encoded probes are provided having forward view capabilities. These probes are configured such that the detection element comprises a plurality of light collecting components, where the distal ends at least partially surround the illumination element and the proximal ends form a linear array that is optically connected to a dispersive component.

Simple monolithic optical element for forward-viewing spectrally encoded endoscopy

Exemplary apparatus, systems, methods of making, and methods of using a configuration in an optical arrangement for spectrally encoded endoscopy (SEE) probe can be provided. For example, the probe can comprise a fixed guiding portion and a rotatable dispersive portion.
