ENDOSCOPE PROBES AND SYSTEMS, AND METHODS FOR USE THEREWITH

摘要

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.

主权项

1. An apparatus comprising:
an illumination unit having at least a first spectrally dispersive grating and a second spectrally dispersive grating structured and positioned such that a first band of spectrally dispersed light propagating from the first spectrally dispersive grating propagates on a different plane than a second band of spectrally dispersed light propagating from the second spectrally dispersive grating, one or more detection waveguides configured to receive a first reflected light and a second reflected light reflected by a sample; and one or more detection units configured to:
detect and correlate the first and second reflected lights and form one or more images with information of at least two colors of light,detect and connect a field of view of light and form one or more images with the connected field of view, ordetect and correlate the first and second reflected lights and form one or more images with information obtained by the one or more detection units at different times, wherein the apparatus is configured such that the first and second bands of spectrally dispersed light are spatially separated when incident on the sample.
