摘要
A Spectrally Encoded Forward View or Multi-View Endoscope, Probe, and Imaging Apparatus and system, and methods and storage mediums for use therewith, are provided herein. At least one apparatus or system may comprise a first waveguide; an optical system; and a diffraction grating. The first waveguide may be for guiding light from a light source to an output port of the first waveguide. The optical system may comprise at least a first reflecting surface and a second reflecting surface. The first reflecting surface may be arranged to reflect light from the output port of the first waveguide to the second reflecting surface. The second reflecting surface may be arranged to reflect light from the first reflecting surface back through the first reflecting surface to the diffraction grating. The diffraction grating may diffract light from the second reflecting surface in several lights/colors of non-zero diffraction orders in a first direction.
